A growing open-hardware trend is making mainstream microcontroller development boards easier to manufacture, modify, and standardize. The Easyduino project publishes fully open-source KiCad designs that recreate popular Arduino Uno/Nano, ESP32 (including S3), Raspberry Pi Pico (RP2040), and STM32 “Bluepill” boards, while adding practical production upgrades like USB-C. Beyond schematics and layouts, it ships complete fabrication-ready assets—BOMs, centroid files tuned for JLCPCB, gerbers, PDFs, and build notes—bridging fragmented legacy toolchains (Eagle, Altium, older KiCad) into consistent KiCad v8–v10 workflows. Community discussion is driving forks and contributions for corrections and new boards.
WeebLabs/DSPi: A fully featured audio DSP firmware for the Raspberry Pi Pico (RP2040) and Pico 2 (RP2350).
Easyduino is an open-source repository providing KiCad PCB designs that replicate popular microcontroller devboards — Arduino Uno/Nano, ESP32 (including S3), Raspberry Pi Pico (RP2040), and STM32 Bluepill — with USB-C support and manufacturing-ready outputs. The project standardizes divergent original toolchains (Eagle, Altium, KiCad), uses a 4-layer JLCPCB-compatible stackup, and supplies KiCad project files, BOMs, gerbers, PDFs, centroids, and datasheets; differences from originals are documented per board. Built with KiCad v8 and tested on v10, the repo includes nonstandard footprints where needed and guidance for build/production. Contributions via issues or PRs are welcome, though KiCad v10 git utilities may require adding whole projects when changing files. This matters to hardware and maker communities by lowering barriers to PCB replication, customization, and manufacturing.
Open-source Easyduino provides KiCad PCB designs that replicate popular microcontroller devboards — Arduino Uno/Nano, ESP32 (including S3), Raspberry Pi Pico (RP2040) and STM32 Bluepill — with added USB-C support and standardized KiCad v8–v10 jobsets. The repository includes full KiCad projects, nonstandard footprints, BOMs, Centroid files formatted for JLCPCB, gerbers, PDFs, datasheets, photos, and production notes (noting deviations from originals such as component substitutions and 4-layer JLC04161H-7628 stackup). The project aims to unify disparate original toolchains (Eagle, Altium, KiCad), simplify board production with JLCPCB constraints, and invites issues or forks for corrections and new board contributions following the repository’s conventions. This lowers barriers to manufacturing and customization of common devboards.
