16-Channel 12-bit PWM/Servo Driver - I2 C interface - PCA9685 for Arduino Raspberry Pi DIY Servo Shield Module Description : Want to make a hexapod walker? Maybe you're making a piece of art with tons of moving parts, or you need to drive a ton of LEDs with precise PWM output. Your microcontroller has a limited number of PWM outputs, and you find yourself running out! Not with the Adafruit 16-Channel 12-bit PWM/Servo Driver - I2 C interface. With this pwm and servo driver breakout, you can control 16 free-running PWM outputs with just two pins! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these beauties for up to an outstanding 992 PWM outputs.Features : Dimensions (no headers or terminal block) 2.5" x 1" x 0.1" (62.5mm x 25.4mm x 3mm) Weight (no headers or terminal block) : 5.5grams Weight (with 3x4 headers & terminal block) : 9grams This board/chip uses I2 C 7-bit address between 0x60-0x80, selectable with jumpers 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 power-good LED3 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"Chain-able" design 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 pinsi2c-controlled PWM driver with a built in clock. Unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!It is 5 V compliant, which means you can control it from a 3.3 V microcontroller and still safely drive up to 6 V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)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 1.6 KHz12-bit resolution for each output - for servos, that means about 4us resolution at 60 Hz update rate Configurable push-pull or open-drain output Output enable pin to quickly disable all the outputs Instructions for use : (1) Drive board connected to Arduino : The PWM driver board uses the I2 C method, so only four lines can be connected to the Arduino device : "Classic" Arduino pin mode : + 5v -> VCCGND -> GNDAnalog 4 -> SDAAnalog 5 -> SCL Old Mega pin way : + 5v -> VCCGND -> GNDDigital 20 -> SDADigital 21 -> SCLR3 and later Arduino pin method (Uno, Mega &Leonardo) : (These boards have dedicated SDA and SCL pins)+ 5v -> VCCGND -> GNDSDA -> SDASCL -> SCLVCC pin is only for the chip power supply, if you want to connect the servo or LED lights, use the V + pin power supply, V + pin supports 3.
