First up, the PCA9685 16×12-bit Servo PWM board (above), which is capable of driving up to 16 servo motors at once. All those motors need a good amount of current, so it’s best to use a separate power supply — easily added with our 2.1mm-to-terminal block adapter (above, top). The PCA9685 Fritzing part behaves just like the real part — all the GND and V+ lines are bussed together, as are the I2C terminals on either end.
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.
