Exploring the hardware that runs MicroPython

Originally designed for the Pyboard, MicroPython now exists for many other microcontrollers. You may use tools such as uPyCraft (as done in the preceding example), the NODEMCU Firmware Programmer, Thonny, or the popular Python esptool (pip install esptool) to flash MicroPython onto a microcontroller.

In this section, we will take a brief look at a few of the microcontrollers that support MicroPython.

Pyboard

The first microcontroller to support MicroPython was the Pyboard. It comes with a Micro SD slot for more memory, a 3-axis accelerometer, analog-to-digital converters, digital-to-analog converters, and four built-in LEDs (red, green, yellow, and blue).
