PCA9685 16-Channel 12-bit PWM Servo Motor Driver I2C Module

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
