From the project

A modular game console based on RP2454

- Resistor based module idnetification at start up - 2" 240x320 ST7789 LCD panel - RP2354 MCU - Easily adaptable module standard - Rust firmware with embassy and slint-ui

I really like the idea of modules, and modular things, and making people work together, so I made this.

The console has two 4 layer PCBs designed in KiCAD, a main-board and a daughter-board, designed for JLC's basic process.
