Features :
● Adjustable frequency PWM up to about 1.6 KHz
● 12-bit resolution for each output – for servos, that means about 4us resolution at a 60Hz update rate
● Configurable push-pull or an open-drain output
● The output enable pin to quickly disable all the outputs
● Terminal block for power input
● 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
● Chainable design
● A spot to place a big capacitor on the V+ line
● 220-ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial.
● This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers.
