M5Stack is an open-source modular toolkit for IoT developments based on ESP32. This combines the advantages of the ESP32 with a nice case, buttons, displays, and a stackable concept that helps you accelerate your DIY Projects. This section includes tutorials and project ideas using the M5Stack family.
M5Stack has just launched the M5Stack CORE2, an ESP32 based IoT development kit, with a capacitive touch screen that brings users a smoother human-computer interaction experience. As usual, the development kit is compatible with Arduino, MicroPython, and UIFlow.
The M5Stack CORE2 has an ESP32 D0WDQ6-V3 with two Xtensa® 32-bit LX6 microprocessors that can be individually controlled. The clock frequency is adjustable from 80MHz to 240MHz.
M5Stack sent me an early sample to play...
I've just upgraded the MicroPython camera module for ESP32. The OV2640 uses I2S and two months ago, I wrote/updated the I2S connector to support more boards (check the hardware and software section below).
This time with the help of @joerggollnick, the driver was extended to include the following camera settings:
vertical flip, and
Hardware and Software
The M5Camera is a camera unit based on ESP32 chip has an OV2640 and also includes a PSRAM. As you may already know, M5Stack is an open-source modular toolkit for IoT developments based on ESP32. There are four versions of this camera (see Fig. 1). I got the M5-Camera B and this is a tutorial to use the camera to generate timelapse videos. However, this module doesn't have a microSD slot. Therefore, the application will publish the photos on an MQTT Broker, so that an MQTT subscrib...
This tutorial updates the article: MicroPython: Taking photos with an ESP32-CAM, in which I described the steps to add support to the ESP32-CAM on MicroPython. In this tutorial, I've updated the driver, and more cameras/boards are now supported. I tested the driver on the ESP32-CAM and the M5CAMERA (model B). It should also work with every board that has an OV2640, and it can be extended to support the OV3660 (I didn't find any board with an ESP32 that uses this camera)....
Last week, I've received a brand new M5Stack ATOM Echo parallel to the market launch (see Fig. 1). You might already know the M5Stack company. They make robust and open-source development kits with stackable modules. The kits allow you to make rapid and high-quality prototypes.
Today, the M5Stack launches the ATOM Echo. Check out this video, and see how it works with MicroPython:

I've just updated the LoRa/LoRaWAN repository for MicroPython and added a configuration that works on the M5Stack Fire using the LoRa868 Module. Therefore, this will help you connect the M5Stack Fire to the "The Things Network (TTN)"!
If you're new to MicroPython read this tutorial: Tutorial: Getting Started with MicroPython on ESP32, M5Stack, and ESP8266If you want to know more about the LoRaWAN and MicroPython, read this article: Tutorial: ESP32 running MicroPython sends data o...
Two weeks ago, I published a tutorial that explains how to connect an M5Stack running MicroPython to the Google Cloud Platform using the IoT Core, and I did mention that upcoming tutorials will examine the following topics:
Spring in Europe has already started, and many people are having allergy problems. Therefore, I thought of making a project to measure air quality and collect this data to train a model that can tell me, when is the best time to open my apartment windows to let some fresh air into the apartment and thus minimize possible allergy attacks and sneezing! Like almost everyone right now (thanks to COVID-19), I'm working from home and this beautiful...
This tutorial is about programming the M5Stack Atom using MicroPython to transfer data to a LoRaWAN gateway. The gateway is then connected to the "The Things Network" (TTN) to process the data.
Before you start reading, check out the video of this setup!
The M5Stack ATOM Matrix is the most compact development board in the M5Stack development kit series with a size of only 24 x 24 x 14 mm and a weight of 14 g.
- 6 GPIO (Dupont Pins)
- GROVE/4Pin PH2.0 interface
- 5 x ...
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...
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):

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...
