Last year, we reviewed the MR60FDA1 60GHz mmWave fall detection sensor kit, which utilizes the XIAO ESP32C3 module as its core. This module, featuring both Wi-Fi and Bluetooth connectivity, opens up various IoT applications. Now, Seeed Studio has introduced advanced mmWave sensor modules specifically designed for enhanced fall detection and heartbeat monitoring. The MR60FDA2 is optimized for fall detection, while the MR60BHA2 is designed for heartbeat monitoring. Powered by an ESP32-C6 WiFi 6 and RIS-Bluetotoh LE microcontroller, these modules offer reliable detection for real-time fall monitoring and accurate heartbeat tracking. They also feature customizable RGB LEDs and ambient light sensors, providing additional flexibility. With expansion options via Grove GPIO ports, these versatile modules are well-suited for applications like smart home integration and healthcare monitoring. Previously, we covered the RoomSense IQ and the DesignCore RS-6843AOPU with mmWave technology. The RoomSense IQ is an ESP32-S3-based modular room monitor with mmWave radar presence [...]

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 [...]

The NXP RW612 is an Arm Cortex-M33 SoC with three radios, namely WiFi 6, Bluetooth 5.4, and 802.15.4 for Thread and Matter connectivity. It also has a small sibling called the RW610 without the 802.15.4 radio. I first came across RW61x chips, when Debashis wrote about the Trimension SR250 UWB chip mentioning it can work with “host processors like NXP’s i.MX, RW61x, and MCX families”. I initially thought it was a typo for the iW612 tri-radio solution introduced in 2022, and the RW612 is indeed similar, but it’s a complete wireless microcontroller/SoC with an Arm Cortex-M33 application core so it can be used independently as a host instead of a companion chip. NXP RW612 and RW610 specifications: MCU sub-system Core – 260 MHz Arm Cortex-M33 with TrustZone-M Memory On-chip 1.2 MB SRAM PSRAM interface for memory expansion Storage – Quad FlexSPI Flash XIP with on-the-fly decryption Peripheral interfaces Up to [...]
