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 [...]

Conexio Stratus Pro nRF9151 is an IoT development kit based on Nordic Semi nRF9151 system-in-package (SiP) with LTE-M/NB-IoT, DECT NR+, and GNSS connectivity designed for battery-powered cellular-connected products such as asset trackers, environmental monitors, smart meters, and industrial automation devices. It’s offered with the “Stratus Pro Expansion Dock” allowing users to add WiFi 6 through an nRF7002 expansion board and various other modules via Grove, Qwiic, MikroBus, and Seeed Studio’s XIAO connectors or sockets. It’s an update to the original Conexio Stratus Pro based on nRF9161 introduced last June with a very similar feature set. Let’s have a deeper look to find out any potential differences between the two versions of the devkit. Conexio Stratus Pro nRF9151 specifications (with changes highlighted in bold or strikethrough): System-in-package – Nordic Semi nRF9151 SiP MCU – Arm Cortex-M33 clocked at 64 MHz with 1 MB Flash pre-programmed MCUBoot bootloader, 256 KB RAM Modem [...]

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 [...]

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 [...]

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 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 [...]
