The brand new Raspberry Pi Pico kit based on the High-Performance Raspberry Pi RP2040
An alternative to Arduino: You can use the RP2040 to run less complex projects when you don’t need the size and power of a full Raspberry Pi, but don’t want to develop in an Arduino platform.
Thoroughly documented: The RP2040 is accompanied by incredibly thorough documentation for both its MicroPython SDK and its C/C++ SDK.
