Adafruit 16-Channel 12 Bit PWM/Servo Driver
Adafruit 16-Channel 12 Bit PWM/Servo Driver
Product Description The handy Adafruit PWM and Servo Driver Breakout is an i2c-controlled PWM driver with a built-in clock. This means that unlike the TLC5940 family, you don't need to send continuous signals to connect your microcontroller, it's completely free running. With just two pins, you control 16 free-running PWM outputs. You can even connect 62 breakouts to control up to 992 PWM outputs. It is 5V compliant, meaning you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good if 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 them on a single i2C bus, a total of 992 outputs - that's a lot of servos or LEDs. Adjustable frequency PWM up to approx. 1.6 KHz. 12-bit resolution for each output - for servos, this means about 4us resolution at 60Hz refresh rate. Configurable push-pull or open-drain output enable output pin to quickly deactivate all outputs. 3-pin connectors in groups of 4 so you can plug in 16 servos at once (servo connectors are a little wider than 1/8" so you can only stack 4 side by side on 1/8" header). A place to put a large capacitor on the V+ line (in case you need it). Solder bridges for the 6 address selection pins. This product comes with a fully tested and assembled breakout as well as 4 pieces of 3x4 male straight header (for servo/LED connector), one 2-pin terminal block (for power) and one piece of 6-pin 0.3cm header (for plugging into a breadboard). A little light soldering is required to assemble and customize the board by attaching the desired headers. But it's a 15-minute task that even a beginner can do. Set contains: 1 x fully tested and assembled. 4 x Straight Plug (3 x 4) 1 x 2-pin terminal block 1 x 0.3cm Header
