 When a featherboard's too big, but you need more pins than a cutie pie has to offer, Itsy Bitsy is the go-to option, the happy medium. And Itsy Bitsy is now available in the tasty RP2040 flavor, which means it has a lot more pep in its step and tricks up its sleeve. A dual Cortex M0 Plus running at 125 MHz, 264K of SRAM and 8 megs of flash. In addition to standard niceties like the built-in NeoPixel, the Bitsy can speak 5-volt logic on pin 5, so there's no need to add any additional level shifting hardware, which is nice. And bonus, that boot select button can be read and used within your code. So I don't have to add a push button, but I do have to figure out how I'm going to use 16 channels of pulse width modulation.
