This matrix has 1024 total LEDs (512 red and 512 yellow) arranged in a 16×32 grid on the front. On the back there are two IDC connectors (one input, one output: you can basically chain these together) and each panel has 4 x HT1632 matrix scanning processors on the back to manage the display mutliplexing. Note that while you can dim the entire panel to one of 16 brightnesses, you cannot individually dim LEDs to create color gradiants. But,the good news is once you write the LED on/off settings you want, the multiplexing is done for you. These displays are ‘chainable’ – connect one output to the next input and add an extra chip-select wire per extra panel
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.
