Review of SONOFF BASICR4 Smart Switch and S-MATE2 Smart Remote Control

We’ve received two new devices from SONOFF for testing, namely the BASICR4 Smart Switch and the S-MATE2 Smart Remote Control. For those familiar with SONOFF devices, the Basic series is well-known as it was one of the initial products SONOFF introduced to the Smart Home market. It’s a Wi-Fi switch that can be used for various purposes, including controlling lights, fans, and other electrical devices. The BASICR4 model enhances capabilities while reducing costs compared to its predecessor. The S-MATE2, on the other hand, is the second version of a simple Remote Controller powered by batteries. It wirelessly connects to other SONOFF devices that support the eWeLink Remote Gateway feature, enabling full control within the same ecosystem. This expands its usability across different devices. Let’s delve into the details. SONOFF BASICR4 Introduction The Basic series has been a long-standing Wi-Fi Switch family allowing control of electrical devices through the eWeLink app […]

WeAct ESP32H2-N4 – A $6 Bluetooth 5.2 LE, Zigbee 3.0, and Thread development board

WeAct ESP32H2-N4 is a low-cost ESP32-H2 development board with Bluetooth 5.2 LE, Zigbee 3.0, and Thread connectivity with a design very similar to the one of Espressif Systems’ ESP32-H2-DevKitM-1 development board, but sold for just $5.70 plus shipping. The ESP32-H2 wireless microcontroller is basically the little brother of the ESP32-C6 without WiFi and aims at low-power nodes in short-range IoT networks. We have previously seen it in Espressif hardware like the aforementioned ESP32-H2-DevKitM-1 and the ESP Thread Border Router board combining ESP32-H2 & ESP32-S3 wireless chips, but so far not in third-party boards, and WeAct ESP32H2-N4 changes that. WeAct ESP32H2-N4 specifications: Wireless module – ESP32-H2-MINI-1 MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 KB SRAM, 128 KB ROM, 4 KB LP memory, Bluetooth 5.2 LE/Mesh and 802.15.4 (Zigbee/Thread/Matter) radios. Storage – 4MB flash storage PCB antenna Dimensions – 13.2×16.6×2.4 mm USB – 2x […]

Giveaway Week 2023 – Elecrow ESP32 Terminal with a 3.5-inch touchscreen display and OV2640 camera

If I remember correctly, Elecrow sent me an end-of-year gift with a notebook (paper style), a pen, and a 3.5-inch ESP32 terminal. I had completely forgotten about it, and while wondering what I would give for Giveaway Week 2023, and looking around in drawers and on shelves, I found an “ESP32 Terminal” package, and I was like “What the F is that and where is it coming from?”. Long story short, the 6th prize of this year’s giveaway week is Elecrow’s ESP32 Terminal with a 3.5-inch touchscreen display that also comes with a front-facing OV2640 camera and six Crowtail connectors for expansion plus a LiPo battery connector. Elecrow ESP32 terminal specifications: Wireless module – ESP32-S3 2.4 GHz Wi-Fi and Bluetooth 5 (LE) module with 16MB flash and 8MB PSRAM Storage – MicroSD card slot Display – 3.5-inch TFT LCD display with 480×320 resolution (ILI9488 driver), capacitive touchscreen Camera – 2MP […]

ESP32-C6 ESP32-H2 ESP32 Arduino Core 3.0.0

November 3, 2023

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 […]

WeAct launches $6 ESP32-C6 development board, ESP-IDF 5.1 framework released

As expected, Espressif has just released the ESP-IDF 5.1 framework with ESP32-C6 and ESP32-H2 support, so more ESP32-C6 boards should become available, and after Olimex ESP32-C6-EVB launched earlier this week, we’ve noticed WeAct had introduced a low-cost ESP32-C6 development board that sells for just $6.43 plus shipping a few weeks ago. WeAct ESP32-C6 board The WeAct board offers 2.4 GHz WiFi 6, Bluetooth LE 5.0., and Zigbee/Thread connectivity through the ESP32-C6-WROOM-1 module, two USB-C ports, two 16-pin headers for GPIOs, and if it looks familiar, it’s because it closely follows the design of the official ESP32-C6-DevKitC-1 development kit, albeit with some small modifications. WeAct ESP32-C6 board specifications: Wireless module – ESP32-C6-WROOM-1 with ESP32-C6 single-core 32-bit RISC-V clocked up to 160 MHz, with 320KB ROM, 512KB SRAM, low-power RISC-V core @ up to 20 MHz Wireless – 2.4 GHz WiFi 6, Bluetooth 5.0 LE, 802.15.4 radio for Zigbee 3.0 and Thread.
