What is a Raspberry Pi Pico?

It is a microcontroller board that is based on the Raspberry Pi  RP2040 microcontroller IC. It is a low-cost, reliable, high-performance, and easy-to-use microcontroller board. This board is designed in such a way that either you can solder pin header or you can directly solder surface mount sensor to it. Pico also consists of an SMPS which is capable of providing stable 3.3 volts to the module. You can easily power the board either with a single li-ion cell or with three AA cells.
