Frequently Asked Questions

What kind of ESP32 board does MicroPython support?

The MicroPython software supports the ESP32 chip itself and any board should work. The main characteristic of a board is how the GPIO pins are connected to the outside world, and whether it includes a built-in USB-serial convertor to make the UART available to your PC.

How do I install micropthon on my ESP32 microcontroller?

MicroPython should now be installed on your ESP32 microcontroller. To make sure the MicroPython installation was successful, we'll connect to our ESP32 using a tool called PuTTY. Now that Micropthon is installed on our ESP32 microcontroller, we can communicate with our ESP32 over a serial connection.

How many UART Controllers does the ESP32 chip have?

The ESP32 chip has three UART controllers (UART0, UART1, and UART2), each featuring an identical set of registers to simplify programming and for more flexibility. Each UART controller is independently configurable with parameters such as baud rate, data bit length, bit ordering, number of stop bits, parity bit etc.

How to run your own Python scripts on ESP32 board?

When you setup MicroPython on your ESP32 board, it will run boot.py on every boot, including wake-boot from deep sleep, and main.py after that. Therefore, in order to run your own Python scripts on your ESP32 board, you need to get these two files into your ESP32 board. Installing Remote MicroPython shell on your Python virtual environment
