- This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers.
- Terminal block for power input (or you can use the 0.1″ breakouts on the side).
- Reverse polarity protection on the terminal block input.
- Green power-good LED.
- 3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1″ so you can only stack 4 next to each other on 0.1″ header.
- “Chain-able” design.
- A spot to place a big capacitor on the V+ line (in case you need it).
- 220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivialits completely free running!
- 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 – that’s a lot of servos or LEDs.
- Adjustable frequency PWM up to about 1.6 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.

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.
