Keyboards

This board has PCBA files. So it the following components can be assembled by the factory: - Diodes - Shift register - Down facing LEDs (ws2812b) - FPCs (For attaching Cirque or another pointing device)

BOM: - 1x Helios MCU (to get all features) - Any RP2040 other MCU with the bottom 5 pains available could also be used but that will lead to losing the top right encoder - 1x PWM3360 sensor and its lense - 2x encoders - 1x Scroll ring encoder - 1x Pimoroni Haptic feedback board (optional, needs a separate case files WIP) - 1x WaveShare 1.47inch LCD Display Module 172x320 (optional, needs a…
