Chess board: common questions

What microcontroller does the Chess board use?

The Chess board is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the Chess board?

The Chess board measures 317.5 × 228.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Chess board?

461 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Chess board design files?

From the shuki25/chess-board-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Chess board design in my own project?

The repository has no license, so all rights stay with shuki25. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Chess board 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.
