“MicroPython is a subset of the Python 3 language that has been pared down to run efficiently on several microcontrollers. If you are familiar with Python or looking for a quick way to write code for a microcontroller (that isn’t C/C++, Arduino, or assembly), MicroPython is a good option.
Some development boards, like the pyboard and micro:bit, are capable of running MicroPython out of the box. Others, like the Teensy or ESP32, will require that you load the MicroPython interpreter onto the board first before it will run your MicroPython code.”
