Hardware prototypes and small batches, built in Shenzhen.
Anvol is a U.S.-registered company supported by engineering and supply-chain operations in Shenzhen, China. Send what you have, and our engineers close the engineering gaps, build and test it, and run the small batch. No minimum order; you pay in USD to our US entity.
What you can send
- An idea or a sketch
- A development board build (ESP32, STM32 and similar)
- A partial PCB, CAD files or a BOM
- A working prototype that needs to become repeatable
What our Shenzhen team does
- Engineering & prototype
- Check architecture, parts, fit and testability before anything is built, then build it. More →
- PCB / PCBA & sourcing
- Boards, assembly and parts purchasing. More →
- Firmware
- ESP32/STM32 firmware, drivers, BLE/Wi-Fi, OTA and factory tests. More →
- Enclosure
- Enclosure and product integration. More →
- Small batch
- Parts purchasing, assembly on partner lines, every unit tested and packed, with a batch record. More →

Who does the work
- Zisheng Li, engineering lead
- Embedded systems. 20+ hardware products built, including the logic analyzer, tracked robot and line-following car above. Named inventor on 8 granted patents.
- Our engineering team
- 200+ documented open-source hardware projects under FreakStudio, alongside electronics, firmware and mechanical work for clients. Verifiable work →
- Where it is built
- Electronics benches in Shenzhen where our engineers build and debug, and the tool rooms, board and assembly lines we order from. You see each process, not the factory's name. Factories →
How it starts
- Send what you have through the project form, by email or on WhatsApp.
- If you ask, we send the NDA first. We sign it before we open any file.
- We reply within 12 hours, list what is missing and suggest the next build step.
- You get a written scope with price and date before any work starts. Major scope changes are re-quoted before work continues.
Questions
No. We can start with a single prototype and continue into small-batch production after you approve it.
You do. We sign an NDA before we open any file. The project-specific design files, drawings and tooling belong to you; our general tools and libraries stay ours.
Not from the small-batch prices on this site. None of our priced builds were made at that volume. A larger run is quoted for its own quantity.
No. Certification testing (FCC/CE) is done by a test lab and quoted separately when a product needs it.
