How Much Does It Cost to Get a Prototype Made? Smart Devices in 2026

Getting a works-like smart device prototype made costs about $275 to $660 in parts and fees at October 2026 prices, plus engineering time. Each engineer-week costs about $1,400 at Upwork's median rate for embedded engineers and about $3,500 at a US employer's cost, per BLS. One engineer-week costs more than all the parts, so the number of engineer-weeks sets the total. The main board alone ranges from a $13.90 ESP32-S3 camera board to a $399 NVIDIA Jetson kit. Two large costs arrive only at production: radio certification and injection-mold tooling. One US lab listed $6,500 to $12,000 in April 2025 for FCC certification of a wireless device, depending on its radio module. Protolabs lists molded parts from about $1,495.

A works-like prototype does what the final product will do. It is built from development boards, a simple custom circuit board, and a printed case, before any engineering for factory production.

Cost to get a prototype made: six cost lines for a smart device

A founder can price a smart device prototype as six cost lines. Five belong to the prototype, and certification belongs to production. The BOM (bill of materials) is the list of every part in the device and its price.

Cost line Stage Example price Source, date
Main board and parts (BOM) Prototype $13.90 (ESP32-S3 camera board) to $399 (Jetson Orin Nano Super kit) Seeed Studio, NVIDIA, Oct 2026
2-layer PCB, made and assembled Prototype From $2 for 5 boards; assembly setup $8.18 plus stencil $1.53 JLCPCB, Sep–Oct 2026
Enclosure Prototype (3D print), production (molds) 3D printing from about $95; injection molding from about $1,495 Protolabs, Oct 2026
Cloud and companion app Prototype Apple $99 per year, Google Play $25 once; device connectivity about $0.55 a month for ten devices Apple, Google, AWS, Oct 2026
Engineering time Prototype $35/h (Upwork median) to about $88/h (US employer cost); €91/h (DACH freelancers) Upwork, BLS, freelancermap, 2025–2026
Certification (FCC/CE) Production $6,500–$12,000 for FCC on a Wi-Fi or Bluetooth device, with or without a pre-certified module Compliance Testing LLC, Apr 2025

Dev boards and BOM: $14 to $399 for the main board

A development board (dev board) is a ready-made circuit board that carries the main chip, power, and connectors. It lets a prototype run before anyone designs custom electronics. This article prices three dev boards, one for each AI performance tier.

  • Seeed XIAO ESP32S3 Sense, $13.90. It carries an ESP32-S3 microcontroller (a small chip that runs one program without an operating system), a camera, and a microphone.
  • Raspberry Pi 5, $110 for the 4 GB model. It is a credit-card-size computer that runs Linux, a full operating system. Raspberry Pi lists Camera Module 3 from $25.
  • NVIDIA Jetson Orin Nano Super Developer Kit, $399. It is a Linux computer with an NVIDIA graphics processor built for AI work.

Board prices moved during 2026. The 4 GB Raspberry Pi 5 launched at $60 in 2023 and cost $110 by April 2026, after three increases since December 2025. Raspberry Pi blames LPDDR4 memory, whose price rose sevenfold in a year. NVIDIA raised the Jetson Orin Nano Super kit from $249 to $399 in July 2026. Re-price the BOM before every order.

AI feature cost: ESP32-S3 vs Raspberry Pi 5 vs Jetson

On-device AI means the model runs on the device itself, not on a cloud server. What the AI feature must recognize decides which board tier the prototype needs.

ESP32-S3. It has 512 KB of internal SRAM, the fast working memory, plus vector instructions that speed up neural networks. Espressif's ESP-SR library runs a wake word and up to 300 spoken commands offline on this chip. Espressif's pedestrian detector takes about 130 ms per 224×224-pixel frame, or about 8 frames per second. A general object detector, YOLO11n, takes about 6.4 seconds per 320×320 frame on the same chip. The ESP32-S3 can tell that a person is in view, but it cannot track many kinds of objects in live video.

Raspberry Pi 5 with AI HAT+. The AI HAT+ is an add-on board with a Hailo-8L accelerator chip rated at 13 TOPS; it launched at $70 in October 2024. Raspberry Pi's product page still lists it from $70. TOPS (trillions of operations per second) is a rough measure of AI speed. Hailo lists 110 frames per second for YOLOv8s, a common object detector, measured on the accelerator at 640×640. The 4 GB Pi, Camera Module 3, and AI HAT+ together cost $205.

Jetson Orin Nano Super. NVIDIA lists 67 TOPS (sparse) for the $399 kit. NVIDIA says it runs language and vision-language models of up to 8 billion parameters. It draws 7, 15, or 25 W, depending on the power mode. At 7 W, a 37 Wh battery (a 10,000 mAh power bank at 3.7 V) lasts about five hours before conversion losses. A Jetson product either plugs into the wall or carries a large battery.

Write your AI feature as one sentence: what it must recognize, how fast, and whether it runs on battery. That sentence picks the tier, and the tier sets the BOM and the power design. For the limits of each tier in more depth, see our ESP32-S3 vs Jetson Orin Nano vs Hailo-8L comparison.

Custom PCB cost: a 2-layer board, made and assembled

A PCB (printed circuit board) is the board that wires chips and parts together. A 2-layer PCB has copper wiring on its top and bottom faces. That is enough to connect ready-made radio modules, sensors, power, and connectors into one prototype board. Whether your prototype needs one yet is a separate decision, covered in Custom PCB Prototype or Dev Board? When to Switch.

JLCPCB, a PCB factory in China, advertises 2-layer boards from $2 for five, with a 24-hour build. Machine assembly (PCBA, a PCB with its parts soldered on) adds fees in its Economic tier. These are $8.18 for setup, $1.53 for the stencil, and $3.07 per "extended" part type, as of September 2026. Extended parts are ones that need extra setup on the placement machines. A board with ten extended part types carries about $40 in fees before the parts and shipping.

US founders pay import duty on top: JLCPCB pre-collects a 35% tariff on US-bound PCB and assembly orders, per its March 2026 update. OSH Park makes bare boards in the US at $5 per square inch for three copies. A 2×2-inch board costs $20 for three, shipping in 9 to 12 days.

A design error means paying these fees again and waiting for another delivery. CortexTech designs 2-layer prototype boards of this kind and brings specialist board designers into the project when a product needs high-speed or many-layer boards.

Enclosure cost: 3D printing for the prototype, molds for production

3D printing builds a part layer by layer from a CAD file, with no mold, so each prototype revision can get a new case. Protolabs, a US service, lists 3D printing from about $95; larger parts and better finishes cost more.

Injection molding forces molten plastic into a machined metal mold, which is how cases are made in volume. Protolabs lists injection molding from about $1,495, and its aluminum molds produce 10,000 or more parts. Steel production tooling requires a capital investment of more than $50,000 for runs above a million parts, per Protolabs.

A mold fixes the shape, and a shape change means paying for mold work again. Keep the case printed until the electronics stop changing. For industrial design of the case, CortexTech brings industrial designers into the project.

Cloud and companion app cost: small bills, real accounts

The cloud backend is the server software that receives device data and passes commands from the app. The companion app is the phone app that controls the device.

AWS IoT Core charges $0.08 per million connection minutes and $1 per million messages; Kinesis Video Streams charges $0.03 per video-call channel a month. Ten devices online all month, each sending 300 messages a day, plus 1,000 relayed call minutes at $0.12 per thousand, cost about $0.55 a month. Servers that run your own backend code are billed separately.

The app stores charge more than the cloud: Apple's Developer Program costs $99 per year. Testers can install a beta app through TestFlight only with that membership. Without it, an Apple account can install your app on up to 3 devices, and the install expires after 7 days. Google Play charges a one-time $25 registration fee.

Budget $124 for store accounts in year one; most of this line's cost is the engineering time to build the backend and the app.

Engineering labor: the line that sets the total

A connected device draws on four kinds of work: firmware (the code on the device), electronics, backend, and the companion app. Each takes engineer-hours, so the team's rate times the number of weeks sets this line.

  • US engineers. The US Bureau of Labor Statistics (BLS) reports a May 2025 median of $60.12 per hour for electrical and electronics engineers. In June 2026, wages made up 68.5% of employer costs for full-time private-industry workers, per BLS. At that share, a median-paid engineer costs an employer about $88 per hour, or $3,500 per 40-hour week.
  • European freelancers. freelancermap's 2026 survey of over 5,000 IT freelancers in Germany, Austria, and Switzerland reports €91 per hour for engineering specialists, or €3,640 per 40-hour week.
  • Freelance platforms. Upwork lists $25 to $50 per hour for embedded systems engineers, with a median of $35 ($1,400 per 40-hour week), from past contracts worldwide.

Ask each team for its estimate in engineer-weeks per kind of work, and compare teams on that number. Our guide to how long each prototype stage takes shows where those weeks go. If you have a device idea, send it to us in three sentences at cortextech.dev. We'll reply with its riskiest part and a plan for a 1–2 week prototype sprint that tests it first.

Production-only costs: FCC/CE certification, tooling, and DFM

Certification is lab testing that proves a device's radio emissions meet a market's rules before it is sold. In the US, the FCC (Federal Communications Commission) sets those rules. In the EU, radio products carry the CE mark under the Radio Equipment Directive (RED).

FCC rules allow a prototype to exist before certification. Section 2.805 permits operating an unauthorized device for evaluation "during developmental, design, or pre-production states." Section 2.803 permits conditional sales, such as pre-orders, with a notice, but prohibits delivery to the end user before authorization. You can build, test, demo, and take pre-orders for a prototype, but you cannot ship it to customers before certification.

Compliance Testing LLC, a US test lab, published these FCC price ranges in April 2025:

  • $3,000–$5,000 for a device without a radio transmitter
  • $6,500–$10,000 for a device built on pre-certified radio modules
  • $9,000–$12,000 for a Wi-Fi or Bluetooth device

SparkFun published a lab quote for its own Bluetooth module in December 2019, before the EU's 2025 cybersecurity rules. FCC testing cost $4,000 and CE radio testing $2,800; with Canadian certification and safety testing, the total came to $12,200. SparkFun says other labs quoted double and triple that amount.

A pre-certified radio module carries its own FCC approval, such as the modular certificate Espressif publishes for its ESP32-S3-WROOM-1U. The module choice made during the prototype sets which of the lab's price bands the product lands in.

The EU added security rules for internet-connected radio equipment on 1 August 2025, through Delegated Regulation (EU) 2022/30 under the RED. On 11 December 2027, the Cyber Resilience Act takes over those requirements. Its duty to report actively exploited vulnerabilities already applies from 11 September 2026. An EU launch adds a cybersecurity assessment to radio testing, so firmware decisions made in the prototype carry into that cost.

Tooling, the molds priced in the enclosure section, also belongs here. So does DFM (design for manufacturing): changing a design so a factory can build it in volume at a target cost. CortexTech hardens a validated prototype to the point where a DFM and manufacturing partner takes over, and connects the founder with one.

Memory cost risk: what CortexTech tests first on a Linux device

We built a connected home-entry device with video calling, on-device AI, and a companion app for a non-technical founder.

Take a different product: a greenhouse controller on a Raspberry Pi 5 that logs sensors, runs watering rules, and serves a local dashboard. Its cost risk sits in a spec the founder cannot judge from the outside: the board's memory size. A prototype built on a 4 GB or 8 GB board proves the software works but does not show how much memory it uses.

In 2026, Raspberry Pi priced each memory size differently. From December 2025 to October 2026, the 1 GB Raspberry Pi 5 stayed at $45. Over the same months, the 2 GB rose from $55 to $77.50, and the 4 GB from $70 to $110. At 1,000 units, the gap between the 1 GB and 4 GB boards is $65,000 at October 2026 list prices. Raspberry Pi's Compute Modules, built to plug into a product's own circuit board, also rose by memory size. In April 2026, their 1 GB versions rose $11.25 and their 4 GB versions $25.

When a founder brings us a device like this, the first thing we test is the smallest board that runs the full software. We run the logging, the rules, the dashboard, and the cloud connection together under the heaviest expected load. We record peak memory use on that board. This first sprint takes 1–2 weeks and comes before anyone designs a PCB or a case.

The result gives the founder a priced choice:

  • Move to a microcontroller if the whole software fits an ESP32-S3, which replaces the Linux board with the $13.90 tier.
  • Keep the 1 GB board if the software fits, at $45, the variant whose price held through October 2026.
  • Budget for 2 or 4 GB if the software needs it, at $77.50 or $110 per board, and re-price before each order.
  • Trim the software, for example by serving the dashboard from the cloud, if one feature pushes memory over a size boundary. The device then depends on its internet connection for that feature.

The method applies to any device: find the part most likely to break the budget, and measure it before paying for the rest.

If you want to know which part of your device carries the most cost risk, send us the idea in three sentences at cortextech.dev. We'll name the part we would test first and outline a 1–2 week sprint around it.

How to budget a smart device prototype

  1. Write the AI feature as one sentence; it picks the main board, from $13.90 to $399.
  2. Add PCB fabrication, assembly, and printed-case fees for each revision, in tens to low hundreds of dollars.
  3. Add $124 for app-store accounts; connecting ten prototype devices costs about $0.55 a month, before backend servers.
  4. Get an estimate in engineer-weeks, and multiply it by the team's weekly cost of $1,400 to over $3,500.
  5. Keep certification ($6,500–$12,000 for FCC on a wireless device) and mold tooling (from about $1,495) in a separate production budget.
