An EVT, DVT and PVT partner with a Shenzhen supply chain
Anvol can be that partner: one engineering lead runs your prototype, EVT, DVT and pilot (PVT) builds in Shenzhen, where our engineers design the boards and firmware, buy every part and manage production on partner lines. You sign with Anvol, Inc. in USD, approve each stage, and get the files and test reports at every step.

What each stage delivers with us
| Stage | What it proves | What Anvol does | You get |
|---|---|---|---|
| Prototype | The idea works in real hardware | PCB, firmware, enclosure and sourcing, built into the first units | Design files and working prototypes |
| EVT | The real design meets its key specs: power, heat, signals, firmware | Revisions and bench tests; on small devices usually inside the prototype stage | Test checklist and report |
| DVT | The near-final product passes reliability tests and the rules of its markets | Validation builds; molds are often made here; certification runs at a test lab, quoted separately | Validated design, test results |
| PVT | The line builds the same unit every time | First article on the partner line, fixtures, work instructions, a pilot batch | Pilot units and a batch record |
| Production | Repeat batches of the approved version | Purchasing, assembly, inspection and packing on partner lines | Tested units and production files |
How you stay in control
- Written scope per stage
- Deliverables, acceptance criteria and price before each stage starts; milestone payments.
- Your approvals
- The prototype, the design before any larger run, every part substitution, and each batch.
- One contact
- One Anvol engineering lead from the first file to the packed batch.
- Your files
- Schematics, PCB files, firmware source, enclosure CAD and BOM are delivered to you.
What we have not shown yet
Our priced builds so far are prototypes and small batches, up to 10 delivered units (the lidar cars). We have not published a run of hundreds of units on this site; a PVT at that size is quoted for its own quantity. Simple products can combine stages: we cut repeated work, not the evidence the product needs.
Not included
- Certification testing (FCC/CE)
- Done by a test lab and quoted separately when a product needs it.
- Shipping and import duties
- Usually arranged by you once units leave the factory.
- Changes outside the written scope
- Re-quoted, with a new timeline, before work continues.
