Makeblock mBot Neo robot review with Smart World Add-on Pack

MakeBlock mBot Neo, also known as mBot2, is an educational robot that builds upon the previous generation mBot1 robot, and the company has sent us a review sample, following our earlier review of the Ultimate 2.0 10-in-1 educational robot kit, along with the Smart World Add-on Pack. The mBot Neo features a new ESP32-based CyberPi control board with WiFi connectivity for IoT and AI support. The robot is also equipped with a 2nd generation Ultrasonic sensor with improved object detection accuracy and status indicator, a built-in 4-ch RGB line sensor that can detect colors, as well as a new drive motor that comes with an encoder for more precise motion control. The mBot Neo robot kit is expandable with metal parts from other Makeblock models, mBuild modules and various electronic modules can be added making it also possible to build custom robots with third-party structural parts. The mBot Neo robot […]

ESP32 Arduino Core 3.0.0 adds support for ESP32-C6 and ESP32-H2

Espressif Systems has now released an alpha version of ESP32 Arduino Core 3.0.0 enabling the new ESP32-C6 and ESP32-H2 targets to be programmed with the Arduino IDE, and including a number of new features made possible by the ESP-IDF 5.1 SDK. Announced in 2021, the ESP32-C6 WiFi 6, Bluetooth 5 LE, and 802.15.4 wireless MCU became available in modules and devkits at the beginning of this year, but so far they could only be programmed with the latest version (5.1) of the ESP-IDF framework, and so was the new ESP32-H2 Bluetooth 5.2 and 802.15.4 (Zigbee/Thread) MCU. But fans of Arduino programming can now rejoice as an alpha version of ESP32 Arduino Core 3.0.0 brings support for the new microcontroller, and a stable release is planned for December 2023. But as you can probably imagine ESP32 Arduino Core 3.0.0 will also bring lots of other changes since the ESP32 Arduino Core […]

Review of the first Matter device by SONOFF – MINI Extreme Wi-Fi Smart Switch (MINIR4M)

We have just received the first Matter product from SONOFF for review, which is the Mini Extreme Switch (MINIR4M) model. Its external appearance closely resembles the Mini Extreme Switch Wifi (MINIR4) which we reviewed previously. They have different colors to distinguish between WiFi (Orange) and Matter (Green). In this review, we have experimented with various Smart Home platforms that support Matter, such as Home Assistant, Apple HomeKit, Google Home, and even their own eWeLink app. Let’s see how their operations and features differ to some extent. Quick intro for Matter. We have heard Matter/Thread together in the news. Matter is a control protocol, while Thread is a communication protocol. Both protocols can work together, or separately. Matter can operate on the top of various communication protocols, including WiFi, Ethernet, BLE, or Thread, with subtle differences such as energy efficiency, network, and resiliency. What’s crucial to note is that Matter acts […]
