Product overview

• I2C-controlled PWM driver with a built in clock• Works with both Raspberry Pi and Arduino• 6 address select pins (up to 62 of these on a single I2C bus - that's 992 outputs!)• Adjustable frequency PWM up to about 1.6 KHz• 12-bit output resolution (about 4us resolution at 60Hz update rate for servos)• Configurable push-pull or open-drain output• Output enable pin

You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! What now? You could give up OR you could just get this handy PWM and Servo driver breakout.

It's an i2c-controlled PWM driver with a built in clock. That means that, unlike the TLC5940 family, 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 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). 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 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. Output enable pin to quickly disable all the outputs

There are 2 places to apply power, one for the PWM output, the other is the VCc supply to the chip. Can I use 5v to supply the VCc?
Asked by: Cj
The power input is located at the top of the board, all others are connected across the board, you should only put the 5v in on the specific ports
