My Corne Cherry v3 setup

• ✅ Corne Cherry v3 board
• ✅ nice!nano V2 Wireless Controller

Backlight

• Configurations

For this set up, the backlight is actually also used as a frontlight. The SK6812 MINI-E RGB LEDs 3535 are mounted on the top of the PCB, facing the keycaps. The WS2812B RGB LEDs 5050 are mounted on the bottom of the PCB, facing the desk. Since ZMK doesn't support per-key RGB backlighting yet, I have to use the same LEDs for both backlight and frontlight.

Troubleshooting

OLED remains blank after EP_OFF

Then flash the firmware, click EP_OFF and EP_ON on the keyboard, then click Reset on the keyboard. The OLED should be back to normal. If not, try to flash the firmware again.
