PCB version 1.0 contains an error. The sanity LED is connected to GPIO0, connect it will prevent the board from booting. Version 1.1 fix this, but version 1.0 is already in production so it needs a manual fix. The LED SHALL be ground driven, on version 1.0 it is +3.3 driven. It's not good, it create a PULL-DOWN. It should be a pull-up.
- Swap 48 and 47 pins.
- 47 (LED-RING) => 48,
- 48 (SDA) => 47
