PCB 1: common questions

What microcontroller does the PCB 1 use?

The PCB 1 is built around the ESP32-DEVKIT-V1, from the ESP32 family.

How big is the PCB 1?

The PCB 1 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB 1?

12 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB 1 design files?

From the Nigonzalezf/Simons-Piano repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PCB 1 design in my own project?

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

Can I test firmware for the PCB 1 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.
