Adafruit 16-Channel 12-bit PWM/Servo Driver – I2C Interface – PCA9685

Features Adafruit 16-channel 12-bit PWM/Servo Driver

• It is an I2C controlled PWM driver with a built-in clock.
• It is 5V compatible. You can control it with 3,3V microcontrollers, yet safely control up to 6V outputs.
• 6 Address Select Pins so you can go up to 62 boards on a single I2C bus. So you have 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.
• Adjustable push-pull or open-drain output.
• Output enable pin to quickly disable all outputs
• Screw terminal for power input
• Reverse polarity protection on terminal block input
• Green Power Indicator LED
• 3 Pin connectors in groups of 4. This way you can connect 16 servos at the same time.
• Linkable design
• A place to place a large capacitor on the V+ line. (in case you need it)
• Series 220 ohm resistors on all output lines to protect them and make driving LEDs easy.
• Solder jumpers for the 6 address select pins
