About Qwiic Twist RGB rotary controller

An ATtiny84 reads a rotary encoder and pushbutton, controls the knob’s RGB light and exposes the result over I2C. Original two-layer design for adaptation to ViaGrid; rerouting and testing are required.

Published design files

Canonical source stays in the upstream git repository (and in WalGit after a successful mirror push). Generated renders and 3D models use artifacts/viagrid/qwiic-twist/f9bbde3fad9b549a7cbdb31b192a003f8ffae182/1c0ee6e443dfb7ca on the artifact CDN and are not checked into git.
