MicroPython has almost all the features of Python, and allows you to easily interact with microcontrollers and sensors, making them accessible to both beginners and experienced Python programmers.
If you are new to MicroPython, I quote the official MicroPython page for you:
MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimized to run on microcontrollers and in "constrai...

This is a tutorial to control and display widgets on an E-INK display using an ESP32. Three widgets are available:
- Weather: weather forecast obtained using the OpenWeatherMap API.
- News: news highlights obtained using the NewsApi API.
- Notes: notes that can be added using a web-server that runs on the ESP32.
The result can be seen in this video:
Thus, in this tutorial, I will try to achieve the following:
- A guide to compile MicroPython to freeze modules;
- A setup guide for ...
LoRa is a wireless data communication technology that enables you to transmit data over a very-long-range (more than 10 km in rural areas) with low power consumption. It uses license-free sub-gigahertz radio frequency bands as the 169 MHz, 433 MHz, 868 MHz for Europe, and 915 MHz for North America.
In October 2018, I published an article about LoRa and ESP32, and I uploaded a project to GitHub. The project includes a SX127x driver for ESP32 running MicroPython. However...
The M5Stack is a modular open-source toolkit for developing IoT applications. It is based on an ESP32, which is the core module and there are a lot of stackable modules that you can use for different projects. This enables to do rapid and high-quality prototyping!
You can program the core device using the ESP-IDF framework, the Arduino-IDE, Blockly or MicroPython. Unfortunately, the BLE is still not available using the official M5Stack MicroPython firmware (forked from LoBo). Howeve...
Holiday season has begun and Christmas and the New Year 2020 are approaching! This means, time to reflect and to clean up code and, therefore, I am updating some of the GitHub's projects to summarize the year. I started with the Christmas lights project! But, this time, I took the M5Stack Fire and a new LED panel (WS2812b - 16x16 pixel) and with the XMasLight project, these are the results (Fig. 1 & 2):
Fig. 1: M5Stack and a new WS2812b Panel (16x16 pixel).
This month, I received the M5Stack FIRE development kit with a PLC base kit from Banggood to review (see Fig. 1). After using it, I can affirm that the M5Stack takes an alternative approach to ESP32 prototyping, because the resulting projects are almost simultaneously finished products. This is possible because the board is housed in a stylish and robust hosing with graphics display, buttons, microSD card slot, USB-C port and speakers. I tested the M5Stack FIRE development kit, and the board i...
