#MicroPython: Tutorial and updated support for ESP32, M5Stack cameras
MicroPython | 5 min | 10721
Last week, I got some time to update the
lemariva/micropython-camera-driverto the actual versions of MicroPython, ESP-IDF, and the camera driver for the OV2640. MicroPython has changed since version 1.14 from
CMakewhich makes it easier to add support for different modules: in this case for the OV2640.
I will sum up the steps to compile MicroPython fr...
#M5Stack Tough: A weatherproof ESP32 Industrial IoT controller
MicroPython, Product Reviews | 2 min | 4396
M5Stack has launched several ESP32 IoT controllers with an integrated touch display such as the M5Stack Core2, the M5Paper, etc. Today, a new Core family member was presented: the M5Stack TOUGH. This device is rugged and dustproof/waterproof with a UV-resistant enclosure sealed with an o-ring and offers waterproof M12 connectors. M5Stack TOUGH is now available for purchase for $49.90 on the company’s store (check out the link below).
The protection against solid ...
#M5Stamp Pico: an ESP32 miniature and powerful module
M5Stack, MicroPython, Product Reviews | 1 min | 4310
M5Stack is a technology company based in Shenzhen China, which specializes in the design, development, and production of IoT development toolkits and solutions, and today they have just launched a new device in its core series: the M5Stamp Pico; and awesomeness comes in small packages.
I thought the M5Stack ATOM would be the smallest core possible, but I was wrong!. The M5Stamp Pico is even smaller and still very powerful. The M5Stamp is the smal...
#Raspberry Pi Pico: The RP2040 meets LoRaWAN
LoRa/LoRaWAN, MicroPython, Raspberry Pi | 5 min | 17801
The "Pico" board with the RP2040 chip developed by the Raspberry Pi Foundation is the latest tiny fast and versatile board in Arduino Nano format. As you may already know, the board can be programmed using MicroPython and C/C++. In this tutorial, I extended the official MicroPython version to support cryptographic primitives, and this unlocks the possibility to connect the board (using the SX1276 chip) to the "The Things Networks" (TTN) - which means LoRaWAN support.
#M5Paper: a Touch EINK device not only for hobbyist
M5Stack, MicroPython | 2 min | 10765
M5Stack has just launched a new device in its core series. This time, the company has combined two great things into a great product: a 4.7" EINK screen with touch capabilities and an ESP32 with 8MB PSRAM. As usual, the device is compatible with Arduino, MicroPython, and UIFlow. It only costs USD69,00.
The M5Paper is a fully programmable and portable device, which is an ideal choice for an IoT application (or you can just use it as an E-reader). The touch EINK screen can b...
#M5Stack: Fresh air checker can help you to stay safe from #COVID-19
Cloud Platforms, M5Stack, MicroPython | 12 min | 219995
Winter is coming and the air-quality inside a closed room could be an index used to estimate the amount of aerosols in it, and hence the risk of Covid-19 infection. In other words, a system of CO2 traffic lights could help to spot potential corona-aerosols!
Where there are many people in a room, there is a lot of exhalation (approx. eight liters of air per minute per nose). This air contains CO2 (carbon dioxide). Long before Covid-19, in Germany, the German Environment Agenc...
#M5Stack: Introducing the new M5Stack CORE2
M5Stack, Product Reviews | 2 min | 10288
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...
#MicroPython: OV2640 camera module extended (M5Camera, ESP32-CAM, etc.)
M5Stack, MicroPython | 2 min | 10800
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

#MicroPython: M5CAMERA timelapse video using MQTT
M5Stack, MicroPython | 4 min | 13436
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...
#MicroPython: Support for cameras: M5CAMERA, ESP32-CAM etc.
M5Stack, MicroPython | 4 min | 19649
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)....
