With the 16×8 LED Matrix Backpack we’ve doubled your project’s matrix capacity by making it super easy to get two separate 8×8 matrices onto one handy board! Matrices like these are ‘multiplexed’ – so to control 64 LEDs you need 16 pins and to control 128 LEDs, you’d need 24 pins. (read more)
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.
