LumenRadio’s nRF52840 based Wireless Modbus module aims to simplify Modbus RTU installations

LumenRadio's W Modbus and W Modbus PRO module's

LumenRadio has recently introduced a Wireless Modbus (W-Modbus) module built around Nordic Semiconductor’s nRF52840 SoC. The module can connect up to 100 nodes, integrates a power amplifier with 100mW transmission power, and supports Bluetooth LE for smartphone connectivity. These features simplify Modbus RTU installations by eliminating traditional control cables, making them ideal for building and industrial automation applications. The company mentions two variants available for this module the ‘W-Modbus OEM Module’ which supports one Modbus client, and the ‘W-Modbus PRO OEM Module’ supporting up to sixteen Modbus clients. Both modules support self-healing, self-organizing mesh protocols that address the issues of network reliability and scalability in industrial environments. The module can also be used for remote monitoring and troubleshooting via smartphones.

AirCard Pro and AirNotch Pro Bluetooth trackers support Google/Apple network integration (Crowdfunding)

Rolling Square introduces its latest Bluetooth trackers – AirNotch Pro and AirCard Pro – designed for use with personal items like keys, wallets, bags, and more. Both trackers are designed for portability, and the AirNotch Pro is designed as a keyring, while the AirCard Pro suits wallets with a thinner, credit card-like design. The products integrate into Apple and Google’s tracking networks, with some features currently limited to Apple. Previously, we covered the SenseCAP T1000, a credit card-sized LoRaWAN GPS tracker powered by Semtech’s LR1110. Several years ago we covered some Bluetooth beacons such as the Puck.js or RuuviTag, but we have yet to explore Bluetooth-only trackers with wireless charging capabilities. Rolling Square AirCard Pro Bluetooth trackers AirCard Pro technical features: Network White version – Operates on Google’s Android Find My Device network (Android 6 or above) Black version – Operates on Apple Find My network (iOS 14 or above) […]

NXP RW612 Arm Cortex-M33 Wireless MCU offers Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios

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 […]

ESP32-C6 WiFi 6 and Bluetooth 5.0 USB-C development board integrates 1.47-inch TFT LCD Display

Waveshare has introduced the ESP32-C6-LCD-1.47 development board powered by an ESP32-C6 RISC-V microcontroller with WiFi 6 and Bluetooth 5 connectivity and equipped with a 1.47-inch display with a 172×320 resolution. With a 4MB flash, an RGB LED, and a microSD card slot for extra storage, this board is suitable for projects that need a compact display, low power consumption, and wireless connectivity such as AIoT applications and human-machine interfaces (HMI). Earlier this month, we covered the ESP32-S3 USB dongle, another development board from Waveshare designed for HMI applications with the same 1.47-inch display with a 172×320 resolution, but a USB Type-A port instead of the USB-C port found in the model covered today. In the past, we’ve written about other ESP32-based development boards for HMI applications, including the LILYGO T-HMI, ESP32-S3-Touch-LCD-4.3B, and Waveshare’s ESP32-S3 LCD Driver Board supporting both square and round displays. Feel free to check them out if […]

M5Stack ESP32-S3-Pico-based devkits: ATOMS3R with 0.85-inch color display, and ATOMS3R Cam with VGA camera

M5Stack ATOMS3R and ATOMS3R Cam are two tiny devkits based on ESP32-S3-Pico system-in-package and a similar design but the first one features a 0.85-inch color color IPS display, while the other is equipped with a GC0308 VGA camera. Both modules measure just 24x24mm with a thickness of around 13mm, integrate BMM150 and BMI270 motion sensors, offer GPIO expansion through female headers and a grove connector, and feature an infrared transmitter and a USB Type-C port for power and programming. Those are the second devkits based on the ESP32-S3-Pico SiP after we covered the tiny OMGS3 module earlier this week. M5Stack ATOMS3R with display ATOMS3R specifications: SiP – Espressif ESP32-S3-PICO-1-N8R8 SoC ESP32-S3 dual-core Tensilica LX7 up to 240 MHz with 512KB SRAM, 16 KB RTC SRAM Wireless – WiFi 4 and Bluetooth 5 LE + Mesh Memory – 8MB QSPI PSRAM Storage – 8MB QSPI flash Display – 0.85-inch color IPS screen […]

Bluetooth 6.0 features accurate two-way ranging using Channel Sounding, latency reduction, improved scanning efficiency, and more

The Bluetooth Special Interest Group (SIG) has just announced the release of the Bluetooth 6.0 Core Specification with features and feature enhancements that include Bluetooth Channel Sounding for two-way ranging between BLE devices, decision-based advertising filtering and monitoring advertisers to improve device scanning efficiency, an enhancement to the Isochronous Adaptation Layer (ISOAL) for lower latency and higher reliability, the LL extended feature set, and a frame space update for throughput optimization. Bluetooth 5.4 was released as a minor update mostly adding electronic shelf label (ESL) support in February 2023, or about 18 months ago, but Bluetooth 6.0 is a major update with the most notable feature being Bluetooth Channel Sounding to enable two-way ranging between two Bluetooth LE devices. It’s not the first time we’ve heard about “Bluetooth Channel Sounding” for distance measurements as it was implemented in WiFi 7/6 and Bluetooth 5.4 chipsets such as Synaptics SYN4382 and Broadcom […]
