What a cutie pie! Or is it... a QT Py? This diminutive dev board comes with a throwback processor - an 8-bit 8051! This tiny core is a big change from something like the the ESP32-S3 QT Py with two 240MHz 32-bit cores, but there's lots of folks interested in the CH552 and given the smol size, it is a nice matchup for a smol board.
