About the Cosmic-Girl-Macropad PCB

Cosmic-Girl-Macropad is an open source PCB design by lastmachine, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 98 × 98 mm, with 31 components from 6 distinct parts.

Other key parts include the MOUDLE-SEEEDUINO-XIAO. By type, the board carries 19 diodes, 10 switches, 1 IC and 1 connector.

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

From the project

A personal cosmic-themed XIAO-RP2040-powered macropad for games, video editing, or anything you'd like to customize. It features 9 MX-style switches, 1 EC11 rotary encoder, and a 128x32 OLED screen. Made using KiCad, Fusion 360, and Visual Studio Code.

Having 9 keys makes it perfect for media editing and streaming; those are the main usages I want to give it. Of course, this macropad would work for anything else that allows custom binds. KMK firmware written in Python, is open to modifications

It is called "Cosmic Girl" because I really like the song of the same name created by the band "Jamiroquai," and also space aesthetics.
