Well it is. Watch: On….off…..On…..On..(DANG). Ok, it’s pretty simple for a single signal, but if you’re wanting to create a bunch of well-timed on/off signals, that gets particularly tricky, even for an Arduino. Enter the PCA9685, and its breakout board from Adafruit. Instead of using up your limited number of PWM lines, or trying to fake it all in software (and using up all the resources on your microcontroller), you can simply pop a signal over to this chip via I2C to tell it which of 16 lines you want to pulse, with 12-bit (4096) levels of accuracy. And it’ll keep doing it, all by itself. Pretty handy. And the PCA9685 can be chained 62 deep, for a total number of control of 992 PWM output lines – that’s impressive! The kit comes mostly assembled, with a set of 3×4 headers for installation of servo/LED plugs, a 2-pin power terminal block, and a 6-pin 0.1″ header for breadboard-compatibility. Features Power input via terminal block or 0.1″ spaced pins Terminal block has reverse-polarity power input protection Green power LED 3-pin connectors in groups of four for easy 16-servo installations Easy chaining of boards Power filtration capacitor installation pads 220Ohm output line projection resistors Solder pad jumpers for address selection Specifications 5V compliant, and still talks to a 3.3V microcontroller. 6 “address select” pins for configuring up to 62 ICs on a single I2C bus PWM frequency adjustable up to approximately 1.6kHz 12-bit frequency resolution (equates to about 4µs resolution at 60Hz refresh rate) Configurable as push-pull or open-drain output Output enable pin available for outside-the-microcontroller “shut it down!” control. 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): 5.5g Weight (with 3×4 headers & terminal block): 9g This product comes with a fully tested and assembled breakout as well as 4 pieces of 3×4 male straight header (for servo/LED plugs), a 2-pin terminal block (for power) and a piece of 6-pin 0.1″ header (to plug into a breadboard). A little light soldering will be required to assemble and customize the board by attaching the desired headers but it is a 15 minute task that even a beginner can do.
