About the Audio module

Audio module is an open source PCB design by hackclub, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 25.5 × 32 mm, with 23 components from 9 distinct parts.

Other key parts include the PCM5102A. By type, the board carries 12 capacitors, 8 resistors, 2 connectors and 1 IC.

It belongs with the audio and displays & leds designs in this gallery.

From the project

A modular game console based on RP2354

- Resistor based module identification 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.
