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:

There are already many tutorials that explain how to boot the Raspberry Pi 4 from an SSD disk without any MicroSD card. This is just another one; but, it includes some tips that I founded on Google, because the other tutorials didn't work, nor did they explain the details.
Let's start with some technical details. The Raspberry Pi 4 has an SPI-attached EEPROM, which contains code to boot up the system and more. The firmware of this EEPROM can be updated to include more functionalitie...

Two months ago, I wrote a tutorial that explains how to get DRM support on Chromium on the Raspberry Pi. If you follow the steps of that tutorial:
you can use the Chromium web browser to play videos from Netflix, Hulu, HBO, Disney+, Amazon Prime, Spotify, Pandora, and many others (see Fig. 1 & 2).

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)....
Together with the Corel USB accelerator, I programmed a YOLOv2 object detector, etc.
The CrowPi kit is magnificent and has everything you need to start playing with the Raspberry Pi. Furthermore, you get everything in a suitcase, that you can close and clean your "mess" in seconds. :)

It is a rainy day and you have a Raspberry Pi, which is running Raspberry OS (Raspbian), and you think: I can make a media center to watch some movies/series. You configure everything, and then you see something like the next picture, every time that you want to watch Amazon Prime, Netflix, etc. using the Chromium Web Browser:

You could install Kodi, LibreElec or OSMC, and you'll be able to watch your series or movie without any problem (using some plugins). But, if you still want to use Raspberr...
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:
