Description

This module is a breakout board for using the NXP PCA9685 16 channel PWM controller. It features 16 fully programmable PWM outputs with a 12-bit resolution giving a total of 4096 programmable steps with a duty cycle being adjustable from 0% to 100%. Additionally, the output frequency of all 16 channels can be programmed from 24Hz to 1526Hz. Intended for controlling the brightness of multiple LEDs, the programmability of its PWM outputs means that it can also be configured for producing PWM signals compatible with driving standard servos. In fact, this module has been designed with this purpose in mind with 16 sets of headers that allow for any servo with a standard header to be directly plugged into the module.

External 5V can be input into the module via the screw terminal for driving large number of servos and PWM devices.

The module only requires two data pins (SDA & SCL) to do the controlling. Open jumper pads on the module can be soldered to change the I2C address (by default 0x40) to one of 62 options, meaning more than one module can be connected to the same I2C bus.

This module can be used by various devices such as Arduino, ESP8266, ESP32 or the Raspberry Pi Pico.
