Smart chessboard controller: common questions
What microcontroller does the Smart chessboard controller use?
The Smart chessboard controller is built around the ESP32-WROOM-32E (8MB), from the ESP32 family.
How big is the Smart chessboard controller PCB?
The Smart chessboard controller measures 89.8 × 92.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Smart chessboard controller?
54 components, from 31 distinct parts. The full bill of materials is listed on this page.
Where can I download the Smart chessboard controller design files?
From the shuki25/smart-chessboard-controller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Smart chessboard controller 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 Smart chessboard controller 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.
