Low-code/no-code platforms keep on coming and Espressif Systems ESP ZeroCode adds to the list. It is a web application designed to prepare Matter-certifiable firmware for ESP32 devices as per the user’s requirements. The website is supposed to streamline the product development where the firmware is developed for you (no need for those costly software/firmware engineers!) and future OTA updates are also guaranteed for a period of three years. It’s a bit similar to the Tuya platform, but for ESP32 devkits, modules, and/or rebranded products with Matter-certified firmware. So I went to the website to give it a try in Firefox in Ubuntu. After registration and login, we are given three options: Your products, Create a new product, and Rebrand a Certified Product I went with the second option and named by new product “CNX Software Gizmo”. In the next step, we can select the device type between socket, plug, light, […]
SONOFF MINIR4M – A Matter-compatible WiFi Smart Switch
SONOFF MINI Extreme (MINIR4M) is the first Matter-certified home automation device from the company and appears to be based on the same hardware design as the SONOFF MINI Extreme (MINIR4) ESP32 WiFi smart switch that we reviewed last March and is still working fine in my bedroom. Support for the Matter protocol means better interoperability with other brands of Matter-certified products, so you should be able to use the MINIR4M wireless switch with a Samsung Matter-certified Smart Home gateway instead, as well as Apple Home, Google Home, Amazon Alexa, and other apps besides the eWelink mobile app. The main visual difference I see between the MINIR4 and MINIR4M is the color with Orange referring to WiFi support and Green to Matter support. SONOFF MINI Extreme (MINIR4M) specifications: MCU – Espressif Systems ESP32 dual-core wireless microcontroller Connectivity 2.4 GHz WiFi 4 Bluetooth LE used for pairing Matter certification Input – 100-240V […]
Olimex ESP32-C6-EVB supports WiFi 6, BLE, Zigbee, comes with four relays, four opto-isolated inputs
Olimex ESP32-C6-EVB is an open-source hardware board based on an ESP32-C6 wireless module with 2.4 GHz WiFi 6, Bluetooth LE, and Zigbee connectivity, and offering four relays and four opto-isolated inputs, as well as further expansion via two UEXT connector. So far we had a limited amount of third-party ESP32-C6 boards, with Espressif making their own module and development board available in January, and 01Space launching a tiny ESP32-C6 board in April, a time when a lot of software work was still needed. But the ESP-IDF v5.1 with ESP32-C6 support is nearing release (now RC2), and the Olimex board may mark the start of greater availability of ESP32-C6 hardware with stable/usable firmware. ESP32-C6-EVB specifications: Wireless module – ESP32-C6-WROOM-1-N4 module with Espressif Systems ESP32-C6 single core 32-bit RISC-V processor @ 160 MHz with 2.4 GHz WiFi 6 1T1R with Target Wake Time (TWT) support, Bluetooth LE 5.0, and 802.15.4 radio for […]
Zvidar Z-GW-V01 Smart Gateway runs Home Assistant on Allwinner A133 processor
Shenzhen Zvidar Technologies’ Z-GW-V01, also known as the Zvidar Smart Gateway is a single board computer powered by an Allwinner A133 quad-core Cortex-A53 processor and running Ubuntu with the Home Assistant open-source automation framework. The SBC provides Gigabit Ethernet, WiFi 5, and Bluetooth connectivity by default, but also supports plenty of optional wireless modules with Z-Wave, Zigbee, Thread/Matter, LoRa, or 4G LTE connectivity that are either soldered to the board connected by a mini PCIe socket. The board also includes a few USB ports, and it’s apparently possible to connect a 7-inch display and/or audio interfaces if needed. Zvidar Smart Gateway (Z-GW-V01) specifications: SoC – Allwinner A133 quad-core Cortex-A53 processor @ up to 1.6GHz with Imagination PowerVR GE8300 GPU with support for OpenGL ES3.2, Vulkan 1.1, OpenCL 1.2 System Memory – 1GB RAM (option for 512MB, 2GB, or 4GB) Storage – 8GB eMMC flash (option for 4GB, 16GB, or 32GB), […]
Broadcom unveils 2nd generation WiFi 7 chipsets: BCM6765, BCM47722, BCM4390
Broadcom has announced its second generation WiFi 7 chipsets: the BCM6765 residential WiFi 7 access point chip, the BCM47722 enterprise WiFi 7 access point chip with dual IoT radios that support simultaneous operation for Bluetooth Low Energy (BLE), Zigbee, Thread, and Matter protocols, and the BCM4390 low-power Wi-Fi 7, Bluetooth, and 802.15.4 combo chip designed for use in mobile devices. This follows the introduction of Broadcom’s first WiFi 7 chipsets in April 2022 with residential and enterprise WiFi 7 access point chips, and a WiFi 7 client chip, but the second generation access point chipsets support 320 MHz 2-stream Wi-Fi operation and add extra features, and the BCM4390 optimized costs bringing WiFi 7 to lower-prices phones and devices. BCM6765 residential Wi-Fi access point chip highlights: CPU – Quad-core ARMv8 CPU with 10Gbps Ethernet PHY WiFi 7 Dual 2×2 tri-band (2.4, 5, and 6 GHz) capable radios that support simultaneous operation […]
