2023 Year in review – Top 10 posts, statistics, and what to expect in 2024

It’s the last day and last article of the year, so we will look at some highlights of 2023, some traffic statistics on the CNX Software website, and speculate what interesting developments may happen in 2024. Looking back at 2023 The semiconductor shortage that had happened since 2020 started to fade away in early 2023, and supplies for most electronics components and devices seem to be adequate at this time, so that was a bright spot this year, and hopefully, it will stay that way in 2024 despite geopolitical tensions. We did not have any super exciting new Arm application processors from Rockchip, Amlogic, or Allwinner announced this year, although the Amlogic S928X penta-core Cortex-A76/A55 CPU started to show up in some 8K TV boxes. The launch of the Raspberry Pi 5 SBC with a Broadcom BCM2712 quad-core Cortex-A76 processor was probably the main highlight for Arm on this side […]

T-Keyboard-S3 4-key USB mechanical keyboard features keycaps with 0.85-inch color display

LILYGO T-Keyboard-S3 is an ESP32-S3 powered USB mechanical keyboard with four keys each equipped with a keycap featuring a 0.85-inch 128×128 color display to show different icons or characters. We have already covered several programmable small mechanical keyboards/keypads or macropads, so the first time I saw the T-Keyboard-S3 I did not think much of it until I read the $65 price tag on Aliexpress which I found excessive for this type of device. That’s only until I realized that each resin keycap has its own color display that the price made sense, and it makes quite a versatile macropad as you could easily program multiple layouts depending on the use case. T-Keyboard-S3 specifications: Wireless module ESP32-S3-WROOM-1 MCU – ESP32-S3R8 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning Memory – 8MB PSRAM Storage – 16MB SPI flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh […]

NORVI ESP-HMI-5C ESP32-based HMI features a 5-inch resistive touchscreen display

NORVI ESP32-based human-machine interface (HMI) solution features a 5-inch LCD with a resistive touchscreen driven by an ESP32-S3 wireless module and support for the LVGL library. NORVI previously brought us some headless ENET industrial controllers including some with Ethernet beside the WiFi connectivity built into the ESP32 microcontroller, but the NORVI HMI device is the first product from the company with a proper display suitable for HMI applications. NORVI HMI (ESP-HMI-5C) specifications: Wireless module ESP32-S3-WROOM32-1-N16R8 MCU – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning, 512 KB SRAM Memory – 8MB octal SPI PSRAM Storage – 16MB flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh PCB antenna Storage – MicroSD card slot (SPI interface) Display – 5-inch LCD Display with Resistive Touch Audio – Built-in Buzzer Communication interfaces – Ethernet (W5500) and RS485 I/Os 4x digital inputs – Range 18V to 32V […]

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 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 […]
