Incomplete design
We close gaps across the board, firmware, enclosure, drawings, and production files.
Small-batch hardware development & production
Prototype to repeatable production
Bring a sketch, dev-board prototype, or partial design. We resolve the gaps, source parts, build prototypes, and run small batches.
The gap we close
Working once is not the finish line
Early hardware rarely arrives with finished drawings, a locked BOM, and factory-ready instructions. We take responsibility for the missing decisions.
Uncertain parts
We find suppliers, identify practical substitutes, and turn scattered purchases into a controlled BOM.
A product still changing
We build a small number, test what fails, revise the design, and repeat before committing further.
A first real batch
We coordinate assembly, inspection, packaging, and delivery so the approved prototype can be built again.
Built by us
Products we designed and shipped ourselves
These are not client projects. Our team took each one through board layout, firmware, enclosure, sourcing, assembly, packaging, and production.
24-channel logic analyzer
100 MHz sampling, 3.3-5 V input, sigrok/PulseView compatible. We designed and produced the board, enclosure, silkscreen, and retail carton.
Flat-frame underwater ROV
Sealed pressure housing, four thrusters, manipulator arm, tether and ground-station software. STM32 control board and firmware designed in house.
Swing-arm tracked robot
Welded and machined steel chassis, dual swing-arm tracks, PTZ camera and e-stop. Mechanical fabrication and electronics integrated as one build.
Lidar line-following car
Custom control board with OLED display, lidar obstacle avoidance, magnetic line tracking and a companion phone app. Board, firmware and app all ours.
Large ROS inspection platform
Mecanum wheels, sprung suspension, extruded-aluminium frame and acrylic body panels, ROS stack on top. Built at a size where tolerances and welding matter.
Wheel-legged inspection robot
Wheeled drive with leg-linkage posture control for ride height, shoulder shake, and jump, plus a WiFi FPV camera for remote inspection.
Our GraftSense Port Dev Kit is used in lab courses at 10 universities and maker clubs at 25 primary schools. Our City Smart kit series ships with customer-specific branding, silkscreen and packaging.
Our projects are hardware-sponsored by DFRobot, Freenove, Waveshare, LILYGO and M5Stack.
How it works
A build process made for change
Send us what you have
Start with a sketch, development-board prototype, specification, Gerber files, or a physical sample.
Close the engineering gaps
We identify what is missing, resolve manufacturability issues, prepare the BOM, and quote the next build.
Build, test, and revise
We build the prototype, test the result with you, and revise the design before production.
Run the small batch
After approval, we coordinate production, inspection, packaging, and delivery on partner lines.
Why Shenzhen matters
One accountable team across the whole build
The advantage is not one factory. It is the speed of finding the right supplier, process, or substitute across a dense manufacturing network.
You work with one Anvol engineering lead while we coordinate the specialists behind the product: electronics, cables, machining, molding, batteries, finishes, packaging, testing, and logistics.
FindQualified suppliers for each process
SubstitutePractical alternatives when a part blocks the build
CoordinateEngineering changes across different vendors
IntegrateOne finished, inspected product instead of loose parts
Our engineering benches and partner lines in Shenzhen. Not stock photos.
Chris Wu is a repeat hardware founder. His previous company reached $300K ARR and went through MiraclePlus, the old YC China. He leads Anvol's engineering team and reads every message himself.
For the supply chain
Work with us, not around us
We build hardware. You sell parts, run tests, make cables, or ship products. When your work touches ours, here is how we fit together.
Referral
Your customer picks a component and then hits an engineering wall. Send it to us. We handle schematic, PCB, firmware, prototype, and pilot run. Your account stays yours. Confidentiality is default. Referral terms are agreed before we start.
Handoff
You do testing, certification, cable, harness, displays, or mechanical. We do PCB, firmware, and prototype. We hand off clean files before your step or pick up after it.
Overflow
Your engineering team is full. A board revision, a variant, a second source, a prototype with no calendar slot. We run it under your specs. Your design stays yours.
Anvol is a hardware development and small-batch production team. Our engineers close the design gaps, then coordinate and inspect specialized partner lines. You work with one accountable team from prototype through production.
That is a normal starting point. Send the sketch, development-board prototype, partial files, or physical sample you have. We identify what is missing and propose the next practical build step.
Yes. Component sourcing is part of what we do, including older and hard-to-find chips. We source in Shenzhen and provide a full bill of materials with the quote.
No. We can start with a single prototype, revise it with you, and continue into small-batch production after approval.
You do. We sign an NDA before we open any file. The design, drawings and tooling belong to you.
Two options. You can contract and pay the partner factory directly while Anvol invoices a separate management fee, with the factory quote visible line by line. Or you can contract with Anvol's US entity and pay one price in USD. Both use milestone-based payments.
