MicroPython Library

The Soldered PCA9685 MicroPython library wraps the PCA9685 in a single PCA9685 class. Construct it, and every channel is ready to drive with raw PWM ticks or a servo angle. On ESP32, ESP8266 and Soldered Dasduino CONNECTPLUS boards it auto-detects the I2C pins; on any other board, pass your own machine.I2C object.
