A minimal RP2040 breakout board wrangled into a Pin Grid Array, with 8MB flash and a maximal dash of retraux style.
PGA2040 is a compact RP2040 breakout intended for the most svelte and embeddable of projects. It contains only the components necessary to run the RP2040 (that's the crystal, flash, regulator and essential support circuits) and it has no fripperies like LEDs, buttons and USB connectors - you'll need to attach your own USB connector to be able to program it.
The benefits of all this drastic pruning are a tiny, 21mm square footprint and lots of exposed RP2040 pins to play with! 30 of them can be used as general purpose I/O (that's four more I/O than on a Raspberry Pi Pico) and 4 are ADC-equipped. It also has the pin labels, because space is tight on this board.
This PGA2040 is programmable with C++, MicroPython or CircuitPython!
