PCA9685 PWM Servo Driver Shield interface PCA9685 (Compatible)

• You do not need to continuously send it signal tying up your microcontroller, its completely free running!
• It is 5V compliant, which means you can control it from a 3.3V Arduino and still safely drive up to 6V outputs
• 6 address select pins so you can stack 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
• 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 and red power-good LEDs
• 3 pin connectors in groups of 4 so you can plug in 16 servos at once
• 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 trivial
• Solder jumpers for the 6 address select pins
