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.

Incomplete design

We close gaps across the board, firmware, enclosure, drawings, and production files.

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 100 MHz logic analyzer with a set of coloured test hooks

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 with four thrusters and a manipulator arm

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 chassis with sheet-metal body and PTZ camera

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.

Four-wheel robot car with a spinning lidar and a custom control board

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.

Two large mecanum-wheel ROS inspection platforms with aluminium frames

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 with linkage legs and hub motors on a factory floor

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

IntegrateOne finished, inspected product instead of loose parts

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.

Start with an NDA →

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.

FAQ

Questions we get before the first call

Something not covered? Ask us directly →

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.
