Features:
- Adjustable frequency PWM up to about 1.6 KHz
- Configurable push-pull or open-drain output
- Output enable pin to quickly disable all the outputs
- 12-bit resolution for each output – for servos, that means about 4us resolution at 60Hz update rate
- 6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs – that’s a lot of servos or LEDs
