MicroPython • Re: I2C PCA9685

Found one of the adafruit PCA9685 boards in a box and connected to a pico.
Minimal wire connection
- pico GND to board GND
- pico VCC 3.3V (header pin 36) to board VCC
- pico SDA (header pin 1) to board SDA
- pico SCL (header pin 2) to board SCL
This adafruit board has I2C pullup on board (and I guess clones do have these too)

I2C scan worked immediately.
