ZkeeShop 2PCS PCA9685 16 Channel 12 Bit PWM Servo Motor Driver Compatible for Arduino Robot Raspberry Pi IIC Interface Module Shield

It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages) 6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs Output enable pin to quickly disable all the outputs Adjustable frequency PWM up to about 1.6 KHz.Configurable push-pull or open-drain output 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
