PCB: common questions

What microcontroller does the PCB use?

The PCB is built around the ESP32-C6-WROOM-1-N8, from the ESP32 family.

How big is the PCB?

The PCB measures 60.7 × 60.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB?

51 components, from 28 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 PCB design files?

From the SIMCA-USI/Giroscopio_PCB_EMT 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 PCB design in my own project?

The repository has no license, so all rights stay with SIMCA-USI. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PCB 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.
