Specifications:
- This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers
- Reverse polarity protection on the terminal block input
- 3 pin connectors in groups of 4
- It is 5V compliant, also 3.3V microcontroller and still safely drive up to 6V outputs
- 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
- Adjustable frequency PWM up to about 1 kHz
- 12-bit resolution for each output – for servos, that means about 4us resolution at 60Hz update rate
- Configurable push-pull or open-drain output
- Output enable pin to quickly disable all the outputs
