⚠️ Note on RGB LED Compatibility (WS2812 or similar)
This PCB includes a BOB-12009 level shifter based on a bidirectional MOSFET. While suitable for I²C, it is not ideal for WS2812-type LEDs, especially when using fast or complex effects. You may experience flickering or signal issues due to slow signal rise/fall times.
✅ Workaround – Skip the level shifter:
If the distance to the first LED is very short (a few centimeters), you can bridge LV2 and HV2 directly and leave the level shifter unpopulated.
👉 Do not install the level shifter in this case – it will interfere with the signal.
✅ Workaround 2 – Use a proper level shifter:
👉 For longer distances or improved reliability, use a proper unidirectional level shifter like the 74AHCT125 or 74HCT14.
