Protogen PCB left: common questions

What microcontroller does the Protogen PCB left use?

The Protogen PCB left is built around the ESP32-C3-MINI-1-N4, from the ESP32 family.

How big is the Protogen PCB left?

The Protogen PCB left measures 87.6 × 92.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Protogen PCB left?

164 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Protogen PCB left design files?

From the Freimor/Protogen_Helmet_1 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Protogen PCB left design in my own project?

Yes, under the terms of its MIT license, which Freimor chose for the repository.

Can I test firmware for the Protogen PCB left 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.
