This is 16-Channel 12-bit PWM/Servo Driver – I2C interface – PCA9685. You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! What now? You could give up OR you could just get this handy PWM and Servo driver breakout.
Programmable fuzzy group (dim) / Flashing LED brightness independent mixed with 1MHz Fast-mode Plus is compatible with high drive capability has 30mA on SDA I2C bus interface to drive a highly capacitive bus. Each LED output can be achieved from the fully closed (the default) to 4096 (12) between the maximum brightness linear programmable brightness.
