Chessconnect uP: common questions

What microcontroller does the Chessconnect uP use?

The Chessconnect uP is built around the ATmega328P-P, from the AVR/Arduino family.

How big is the Chessconnect uP PCB?

The Chessconnect uP measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Chessconnect uP?

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

Where can I download the Chessconnect uP design files?

From the K-0hm/Chessboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Chessconnect uP design in my own project?

Yes, under the terms of its GPL-3.0 license, which K-0hm chose for the repository.

Can I test firmware for the Chessconnect uP without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
