[I completed a helix build, first time soldering SMD.
I flashed both sides, the right hand is working fine, left hand has only 3 leds working (SW6 - SW4).
Key presses get registered and the oled is working aswell.
I resoldered the LEDs on SW3 and SW4 with spare parts to no effect.
What I checked so far:
- Voltage is present on all LEDs
- Data voltage is present
- Diodes are working
- No obvious bridge or short
