V1: common questions

What microcontroller does the V1 use?

The V1 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the V1 PCB?

The V1 measures 50 × 50 mm, has 8 copper layers and is 1.6 mm thick.

How many components are on the V1?

178 components, from 47 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the V1 design files?

From the manyetox/Autonomous-Photonics-Carrier repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the V1 design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the V1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
