 It is the Itsy Bitsy RP2040, a powerful little board. We've got lots of flash on there, lots of GPIO pins, can do circuit Python on there all day long, and I'll show you a little project that I put together because you may ask yourself, well, what kind of project would I want lots and lots of GPIO pins for in a small form factor? So you can see I've got my little Itsy Bitsy plugged into a small breadboard there, and then I'm breadboarding these wires into key bit that I pulled out of an old synthesizer. It's an eight column and eight row diode matrix, so that means I need 16 pins plugged into my Itsy Bitsy. And I have some leftover pins that I decided to plug in a little NeoPixel strip. Using our keypad library, I can read the diode matrix and know which keys I'm pressing. I decided to have it send off MIDI commands and at the same time send commands to my NeoPixels to light up. It's the Itsy Bitsy RP2040.
