Matter 1.3 specification adds support for water and energy management, electric vehicle chargers, and various household appliances

Matter 1.3 Specification

The Connectivity Standard Alliance (CSA) has just announced the release of the Matter 1.3 specification and SDK with energy reporting, support for water and energy management devices, electric vehicle chargers, several new “major appliances”, namely various kitchen appliances and laundry dryers, and various other features. As a reminder the Matter protocol was initially introduced several years ago under the name Project CHIP to improve the interoperability of Smart Home devices from various vendors, so for example, users could connect a Matter-compatible Philips Hue light bulb to a Samsung gateway, or a white-brand Matter sensor with Google Home, etc… Matter started to pick last year with several products launched, and Paisit notably reviewed the MINI Extreme Wi-Fi Smart Switch (MINIR4M), the first Matter device from SONOFF, last October. Matter 1.3 adds various new capabilities and devices. Matter 1.3 highlights: Support for Water and Energy Management Devices Energy Management – Matter 1.3 […]

WeAct ESP32-C6-Mini is the cheapest ESP32-C6 board so far going for less than $4

WeAct ESP32-C6-Mini board

WeAct ESP32-C6-Mini is a small development board based on Espressif Systems ESP32-C6 WiFi 6, Bluetooth, and 802.15.4 wireless SoC that’s the cheapest we’ve seen so far selling for just $3.86 on Aliexpress. WeAct was one of the first companies to launch a third-party ESP32-C6 development board year with the price starting at just $6. I still remember the excitement around the first $5 ESP8266 WiFi 4 module when we first covered it in 2014, and ten years later, we can get a full $4 development board with a more powerful 160 MHz RISC-V microcontroller, WiFi 6, Bluetooth 5.0, and an 802.15.4 radio for Thread, Zigbee, and Matter. WeAct ESP32-C6-Mini specifications: Wireless SoC – ESP32-C6-N4 CPU Single-core 32-bit RISC-V clocked up to 160 MHz Low-power RISC-V core @ up to 20 MHz Memory – 512KB SRAM, 16KB low power SRAM Storage – 320KB ROM, and 4MB flash Wireless – 2.4 GHz […]

ESP32-H4 low-power dual-core RISC-V SoC supports 802.15.4 and Bluetooth 5.4 LE

ESP32-H4 block diagram

Espressif Systems has formally announced the ESP32-H4 low-power dual-core 32-bit RISC-V wireless microcontroller with support for 802.15.4 and Bluetooth 5.4 LE portfolio after having unveiled it at CES 2024. It’s the first Espressif chip to support Bluetooth 5.4 LE with previous models such as ESP32-H2 or ESP32-C6 only supporting Bluetooth 5.0/5.2. Besides BLE 5.4 support, the new ESP32-H4 dual-core RISC-V WiSoC is an evolution of the ESP32-H2 single-core chip with PSRAM support (up to 4MB built-in), additional GPIOs (36 vs 24), touch sensing GPIOs, and some extra security features such as a power glitch detector also found in the recently announced ESP32-C61. ESP32-H4 specifications: CPU – Dual-core 32-bit RISC-V core (at up to 96 MHz) RAM – 320KB KB SRAM, optional PSRAM up to 4MB Storage – 128KB ROM, External flash support Wireless connectivity IEEE 802.15.4 radio with Zigbee and Thread support, Matter protocol Bluetooth 5.4 (LE) radio designed in-house, […]

u-blox ALMA-B1 and NORA-B2, Bluetooth 5.4 LE modules are based on Nordic nRF54H20 and nRF54L15 SoCs

u-blox ALMA-B1 and NORA-B2 modules

Wireless communication solutions provider, u-blox has added two new modules to its Bluetooth LE portfolio with the ALMA-B1 and NORA-B2 modules built upon the latest low-power wireless nRF54 chips from Nordic Semiconductor.  Both modules come in a portable, power-efficient layout and support Bluetooth 5.4 and 802.15.4 (Thread, Matter, Zigbee). The ALMA-B1 and NORA-B2 BLE modules are powered by the low-power nRF54H20 and nRF54L15 SoCs, respectively. This enables them to provide IoT devices with sufficient processing power for edge computing and machine learning without the need for external components. u-blox claims that the ALMA-B1 module provides “more than twice the processing power of previous Bluetooth LE modules” and can replace general-purpose microcontrollers in compact solutions. Also, the NORA-B2 reportedly “consumes up to 50% less current compared to previous generations of Bluetooth LE modules,” leading to longer battery life or smaller batteries in end products. Both modules are classified as open CPU […]

$6.99 Waveshare’s ESP32-C6-Pico Board resembles Raspberry Pi Pico board

Waveshare ESP32 C6 Pico Devlopment Board

Waveshare’s ESP32-C6-Pico and ESP32-C6-Pico-M development boards are equipped with the ESP32-C6-MINI-1 module supporting Wi-Fi 6(802.11ax), Bluetooth 5, Zigbee 3.0, and Thread 1.3, and inspired by the Raspberry Pi Pico form factor. They can be powered either through USB Type-C or an external 5V DC supply connected to the pins. Previously we have written about similar ESP32-C6-based boards like the SparkFun Thing Plus, ePulse Feather C6, and WeAct ESP32-C6 dev board. However, these boards are priced way over the $6.99 that Waveshare is offering. One exception is the DFRobot’s FireBeetle 2 ESP32-C6 board, which cuts costs by using the IC directly instead of the fully shielded ESP32-C6-MINI-1 module. Waveshare’s ESP32-C6-Pico board specifications: Wireless module – ESP32-C6-MINI-1 SoC – ESP32-C6H4 32-bit RISC-V microprocessor up to 160 MHz with 320KB ROM, 512KB HP SRAM, 16KB LP SRAM, 4MB flash Wireless – 2.4 GHz WiFi 6 with Target Wake Time (TWT) support, Bluetooth 5.3 LE and […]
