PCA9685PW 16 Channel 12-Bit PWM Servo Driver I2CModule For Raspberry Pi

Tscinbuny PCA9685PW 16 Channel 12-Bit PWM Servo Shield Driver I2C Interface PCA9685 Module For Raspberry Pi Robot Project Description:Want to make a hexapod walker? Maybe you're making a piece of art with tons ofmoving parts, or you need to drive a ton of LEDs with precise PWM output. Yourmicrocontroller has a limited number of PWM outputs, and you find yourself running out! Not with the Adafruit 16-Channel 12-bit PWM/Servo Driver - 12C 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 output. Features:Dimensions (no headers or terminal block) 2.5"x1"x 0.1" (62.5mm x 25.4mm x 3mm)Weight (no headers or terminal block): 5.5gramsWeight (with 3x4 headers & terminal block): 9gramsThis board/chip uses 12C 7-bit address between 0x60-0x80, selectable with jumpersTZT Terminal block for power input (or you can use the 0.1" breakouts on the side)Reverse polarity protection on the terminal block inputGreen 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" designA 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 TZT Solder jumpers for the 6 address select pins i2c-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, it's completely free running! We Are The Distributor Of TZT Brand In Hong Kong, China It 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) TZT 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 60Hz update rateConfigurable push-pull or open-drain outputOutput enables the pin to quickly disable all the outputsInstructions for use:
