PART FINDER FRIDAY! When we stumbled upon the PCA9685, we knew we found an awesome chip – its got a free-running PWM driver inside with 16 output channels. You can adjust the frequency to up to ~2KHz, so its great for servos, LEDs or anything else that needs a lot of PWMs. Its 16-bit so its really precise and its free-running so you don’t have to clock it. We turned it into a breakout board but it could be a great addition to a robot controller board.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
