- GPIO is 3.3 V only and is not 5 V tolerant.
- SDA (GPIO7) / SCL (GPIO6) are the breakout pads; the onboard STEMMA QT connector is a second I2C on SDA1 (GPIO41) / SCL1 (GPIO40). NeoPixel is on GPIO39, BOOT button on GPIO0.
- Left pads 1-7 top-to-bottom; right pads 8-14 continuing around the board.
