PWM Click Board
The PCA9685PW IC is a 16-channel LED controller that is optimized for Red/Green/Blue/Amber colour backlighting applications. This 12-bit PWM controller operates with a supply voltage range of 2.3V to 5.5V
16 PWM Outputs
PWM click is a straightforward solution to control 16 PWM outputs using a single I2C interface. When used to its full potential the board will be packed with wire jumpers, with the other end of each one connected to anything from a LED driver, a bunch of servo motors, to a robotic arm. The user can connect multiple PWM clicks to get up to 112 PWM outputs—all through a single I2C interface.
Selectable I2C Addresses
The user can connect multiple PWM clicks together using three jumpers in order to specify a different I2C address for each one. You can set up an individual I2C address for each of the connected click boards by soldering the onboard I2C ADR.
3.3v or 5v Power SupplyPWM click is designed to use either a 3.3V or 5V power supply. The user can switch to the required power supply using a PWR SEL jumper.
