TriPad Studio Controller

The TriPad Studio Controller is a professional-grade 3×3 macro pad powered by the ESP32-S3-MINI-1-N8. It gives streamers instant control over scenes, audio, transitions, and streaming state — all in a tiny, elegant hot-swap mechanical package with per-key RGB and three rotary encoders.

100 % open-source and fully replicable: schematics, PCB, Gerber, BOM, and firmware are all included and designed in EasyEDA Pro (perfect for OSHWLab Stars).
