RASP PI PICO
At the heart of the Raspberry Pi Pico, microcontroller board is a custom Raspberry Pi designed chip called RP2040 with a133 MHz clocked ARM Cortex-M0+ dual-core with integrated 2 MB QSPI flash memory for code and data storage.
You can program your Pico by simply connecting it to a computer/notebook via USB and then transferring a previously downloaded UF2 file, which makes it easier to install MicroPython.
You can get detailed info and the file at https://pico.raspberrypi.org/getting-started/.
Micropython is a complete implementation of the Python 3 programming language, you get an interactive prompt (REPL) to execute commands instantly via USB Serial and an integrated file system.
