On the 21st of January, 2021, the Raspberry Pi Foundation released its own [microcontroller] board called the __[Raspberry Pi Pico|RaspberryPiPico]__. Despite its name, the Pico is a __microcontroller__, not a small __microcomputer__ (i.e., a Single Board Computer or SBC) like the [Raspberry Pi], uses a different CPU chipset (the __RP2040__, a proprietary design by the Raspberry Pi Foundation), and is significantly smaller and cheaper than any Pi at ''US$4''.
