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.\u003c\/p\u003e\n\u003cp\u003eThe 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.
