Qualcomm QCC730M dual-band WiFi 4 and QCC74xM WiFi 6, BLE 5.3, and 802.15.4 modules target low-power and IoT edge devices

Qualcomm QCC730M module

Qualcomm has added two new IoT modules to its wireless connectivity product series: the Qualcomm QCC730M ‘micro-power’ WiFi 4 module and the QCC74xM tri-radio module, with both modules designed for smart homes, smart appliances, medical devices, and industrial applications. The Qualcomm QCC730M is a dual-band, micro-power Wi-Fi 4 module with a 60MHz Arm Cortex-M4F MCU, 640kB SRAM, 1.5MB RRAM, hardware crypto accelerator, and secure boot, debug, and storage. Its low-power design is ideal for portable, battery-powered IoT devices like IP cameras, sensors, and smart locks. Based on the Qualcomm QCC730 module, it features a 36-pin LGA package with a PCB antenna or RF connector and supports up to 4MB of optional NOR flash. The Qualcomm QCC74xM is Qualcomm’s “first programmable connectivity module,” integrating a 32-bit RISC-V module, optional stacked memory (PSRAM and NOR flash), and a tri-radio chipset for WiFi 6, Bluetooth 5.3, and IEEE 802.15.4 (Thread and Zigbee). Its […]

SONOFF ZBMINIR2 review – A mini Zigbee switch & Zigbee router tested with eWeLink and Home Assistant

Sonoff ZBMiniR2 Cover

We have received another Zigbee device from SONOFF for review, namely the ZBMINIR2 which we’ll review with both eWelink adn Home Assistant. Many people may be familiar with the first-generation mini Zigbee Switch that SONOFF released in 2020, known as the ZBMINI. ZBMINI was one of the early Zigbee Switch models, which also acted as a Zigbee Router. The ZBMINIR2 is SONOFF’s second-generation mini Zigbee Switch including both software and hardware upgrades compared to its predecessor. Improvements include a smaller size, better signal quality, an increase in the number of supported devices (2x), wider coverage (5x), and additional features. Let’s dive into the details. Unboxing ZBMINIR2 Zigbee switch Inside the box, you’ll find a small user manual and the ZBMINIR2 device as usual. It is notably smaller than the predecessor model, which makes installation much easier in many cases. For example, it can now fit into the wall box behind […]

KAGA FEI ES4L15BA1 is an ultra-small Bluetooth LE 6.0 and 802.15.4 module based on Nordic nRF54L15 SoC

ultra small Bluetooth 6.0 module

Japanese company KAGA FEI has recently unveiled the incredibly small ES5L15BA1 Bluetooth LE 6.0 and 802.15.4 module based on Nordic Semi nRF54L15 ultra-low-power Cortex-M33 wireless MCU. We had previously covered the u-Blox NORA-B2 which I already found pretty small at 14.3 x 10.4 x 1.9mm, but the ES5L15BA1 module goes a step further measuring just 8.55 x 3.25 x 1.00 mm with an integrated antenna which could make it the world’s smallest Bluetooth LE module. KAGA FEI ES4L15BA1 specifications: SoC – Nordic Semiconductor nRF54L15 MCU cores Arm Cortex-M33 with Arm TrustZone @ 128MHz RISC-V coprocessor for software-defined peripheral Memory – 256KB SRAM Storage – 1.5MB non-volatile memory Wireless Bluetooth 6.0 Data rates – 2Mbps, 1Mbps, 500kbps, 125kbps Features AoA / AoD Channel Sounding 802.15.4 radio for Thread / Zigbee / Matter Nordic Proprietary 2.4 GHz protocol up to 4 Mbps Frequency – 2402 to 2480 MHz +8dBm output power Antenna […]

Synaptics Veros SYN4383 and SYN43756(E) SoCs support tri-band WiFi 6E, Bluetooth 5.3/5.4, and 802.15.4 connectivity

Synaptics Veros S0YN4383 and SYN43756(E)

Synaptic has unveiled the SYN4383 and SYN43756(E) high-performance “Veros” SoCs with tri-band Wi-Fi 6E, Bluetooth 5.3/5.4, and an optional 802.15.4 radio. The SYN4383 is an upgrade to SYN4382 SoC that supports 1,200 Mbps 2×2 MIMO Wi-Fi 6E, Bluetooth 5.4, and 802.15.4 for Zigbee and Thread support. It supports real simultaneous dual-band (RSDB) operation and offers “greater system integration”. The SYN43756(E) is similar but lacks an 802.15.4 radio and RSDB support. SYN4383 “Triple Combo 3” Wi-Fi 6E, Bluetooth 5.4, 802.15.4 SoC Synaptics Veros SYN4383 key features: Tri-band 2×2 MIMO Wi-Fi 6E (802.11ax) up to 1200 Mbps throughput, RSDB with 2.4 GHz radio and either 5 or 6 GHz radio, and support for legacy 802.11a/b/g/n/ac WiFi Bluetooth 5.4 (Bluetooth 6.0 compatible) with LE Audio, Channel Sounding for accurate positioning 802.15.4 radio for Thread and Zigbee Application-layer support for Matter-compliant security and interoperability Smart Co-Ex for WiFi/Bluetooth coexistence in the 2.4 GHz band […]

SONOFF ZBMINIR2 tiny Zigbee 3.0 switch also works as a Zigbee router with up to 64 sub-devices

SONOFF ZBMINIR2

SONOFF ZBMINIR2 is a tiny Zigbee smart switch that looks very similar to the SONOFF Zigbee Extreme (ZBMINIL2) but requires a neutral wire and can act as a Zigbee router with up to 64 sub-devices. It also supports new features such as “Turbo mode” for extended range and “detach relay” mode where the states of external switches and relay are separated, so operating the external switch button won’t affect the relay state. The tiny wireless switch can fit into the smallest EU-type/86-type/120-type mounting boxes and works with gateways supporting the Zigbee 3.0 protocol such as ZBBridge Pro, NSPanel Pro, and other compatible Zigbee 3.0 hubs. It also supports external switches (momentary, door, SPDT, and rocker), voice control through Amazon Alexa and Google Home, and like other SONOFF devices is designed to be controlled through the eWelink mobile app by default. SONOFF ZBMINIR2 specifications: MCU – Unspecified – Potentially the same […]

Arduino Core for ESP32 gets a Zigbee wrapper library

Arduino ESP32 Zigbee

Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been working since the release of the ESP-IDF 5.1 framework along with the ESP-Zigbee-SDK for a while, but Arduino support was less straightforward. But this is about to change as an Espressif engineer nicknamed P-R-O-C-H-Y has recently added a Zigbee wrapper library for the ESP-Zigbee-SDK to Arduino Core for ESP32 that works with ESP32-C6 and ESP32-H2 as standalone nodes and other SoC can be used as radio co-processor attached to an RPC (802.15.4 radio layer). The wrapper library currently supports the following: Zigbee classes and all Zigbee roles Zigbee network scanning Allow multiple endpoints on the same Zigbee device (not tested yet) Supported Home Assistant devices On/off light + switch Color Dimmable light + switch Setting Manufacturer and model name Other tasks currently planned include supporting “Temperature sensor […]
