Programming support of Arduino Nano RP2040 (ABX00053 / ABX00052):

a) Arduino IDE: 2.2.x / 1.8.x / web-editor: C / C++ language

b) MicroPython: (no need to compile / upload flashing, No compilation / library compatibility errors)

i) Official MicroPython reference website / Arduino website

ii) Why MicroPython is taking over Arduino IDE:

MicroPython Basics: What is MicroPython? (By Tony DiCola)

Five 5 Advantages of Using Micro Python for Embedded Software Programming

(YouTube video) Time to Say Goodbye to Arduino IDE and Go On to Micropython/ Adafruit Circuitpython?

- Eliminating the library/compiler installation or compiler-version-conflict problems with MicroPython / CircuitPython

- Easier debugging (no need to compile & run to debug - just type your command to debug)

Editing Tools: Ref Arduino Website1, Arduino Website2

c) OpenMV IDE: Python programming
