From the project

OpenDeck-RP2040-v0 is a DIY 9-key macro pad prototype inspired by the Elgato Stream Deck, built around the Seeed XIAO RP2040.

OpenDeck-RP2040-v0 is an early hardware prototype of a DIY macro pad inspired by the Elgato Stream Deck. This project represents my first-ever hardware design, created as a learning experiment using KiCad with no prior background in electronics or PCB design.

The goal of this project was to explore the fundamentals of hardware design, including schematic capture, PCB layout, and basic I/O expansion using a microcontroller.
