WisBlock RAK13004 PWM Module

The RAK13004 adds 16 PWM outputs to a WisBlock node with the PCA9685 from NXP. This allows, for example, the brightness of 16 LEDs to be controlled individually. The module is accessed via I2C.

WisBlock from RAK Wireless is a modular system for building custom LoRaWAN and IoT nodes. Core, sensor and IO modules are plugged onto a base board and screwed in place.
