16-Channel 12-bit PWM/Servo Driver – PCA9685 for Arduino Raspberry Pi



16-Channel 12-bit PWM/Servo Driver – I2C interface – PCA9685 for Arduino Raspberry Pi DIY Servo Shield Module

nDimensions (no headers or terminal block) 2.5″ x 1″ x 0.1″ (62.5mm x 25.4mm x 3mm)
nWeight (no headers or terminal block): 5.5grams
nWeight (with 3×4 headers & terminal block): 9grams
nThis board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers
nTerminal block for power input (or you can use the 0.1″ breakouts on the side)
nReverse polarity protection on the terminal block input
nGreen power-good LED
n3 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
n”Chain-able” design
nA spot to place a big capacitor on the V+ line (in case you need it)
n220-ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
nSolder jumpers for the 6 address select pins
ni2c-controlled PWM driver with a built in clock. Unlike the TLC5940 family, you do not need to continuously send it to signal tying up your microcontroller, it is completely free running!
nIt 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)
n6 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
nAdjustable frequency PWM up to about 1.6 KHz
n12-bit resolution for each output – for servos, that means about 4us resolution at 60Hz update rate
nConfigurable push-pull or open-drain output
nOutput enable pin to quickly disable all the outputs
