Silex SX-SDMAX6E tri-band Wi-Fi 6E + Bluetooth LE module features NXP IW623 SoC, comes in M.2 or LGA package

Silex SX SDMAX6E tri band Wi Fi 6E + Bluetooth LE module LGA(Right) M.2(Left)

Back in August last year, we wrote about NXP’s IW623 tri-band (2.4GHz, 5GHz, 6GHz) Wi-Fi 6E and Bluetooth LE Audio SoC, but at the time, there was no ready-to-use module based on it. Now, NXP has partnered with Silex Technology to launch the SX-SDMAX6E module, available in a surface-mount LGA package or an M.2 2230 Key-E card. The module supports Bluetooth 5.x connectivity via UART and Wi-Fi via SDIO. It operates from a 3.3V supply with 1.8V support on the LGA version. It has an industrial operating temperature range of -40°C to +85°C and is designed for both high-throughput applications, such as video streaming, and low-power, battery-operated devices in harsh environments. It also supports various antenna options, fast roaming, and long-term lifecycle backing through Silex and NXP.

The Ambient IoT Alliance aims to promote and develop standards for batteryless IoT devices using energy harvesting

The Ambient IoT Alliance, or AIoTA, is a global, cross-industry coalition working to promote and develop standards for batteryless IoT devices relying on energy harvesting for power. Ambient Internet of Things (IoT) refers to a class of IoT devices powered by radio waves, light, motion, heat, or any other viable ambient energy source. It is an evolution of legacy IoT and RFID technologies that promises lower costs and high scalability through Bluetooth, 5G Advanced, and the IEEE 802.11bp ambient power communication (AMP) standard. The alliance says its mission is to “promote and support the development of an open, harmonized, and aligned multi-standard ecosystem”. Ambient IoT-enabled devices can gather location, temperature, humidity, and/r other data, and communicate with the wireless infrastructure through a nearby mobile device, wireless access points, domestic appliances, or other standard gateways using a compatible standard. This reduces maintenance costs since batteries do not need to be replaced, […]

xSDR – A tiny M.2 2230 SDR module with Artix-7 FPGA and LMS7002M RFIC (Crowdfunding)

xSDR single sided M.2 software defined radio with 2× RX TX channels up to 3.8 GHz

Wavelet Lab’s xSDR is a tiny, single-sided M.2 2230 software-defined radio (SDR) module designed for integration into laptops, embedded systems, and edge computing devices. A successor to the company’s previous uSDR, the “x” in xSDR stands for “extended,” adding 2×2 MIMO support and a wider frequency range to the same tiny footprint. The module is built around the Lime Microsystems LMS7002M RFIC and an AMD Artix-7 XC7A50T FPGA as found in the LimeNET Micro 2.0 Developer Edition board. This combination allows for a tuning range of 30 MHz to 3.8 GHz and a sample rate of up to 122.88 MSPS, making this SDR suitable for cellular research (LTE/5G), spectrum analysis, satellite tracking, and high-speed data links (with two modules). Wavelet Lab’s xSDR specifications: RFIC – Lime Microsystems LMS7002M programmable RF (FPRF) transceiver IC FPGA – AMD Embedded XC7A50T (Artix-7) with 52,160 logic cells RF capabilities Channels – 2×2 MIMO (2x […]

LR2021 LoRa Plus board combines Semtech LR2021 and Nordic nRF54L15 for high-speed FLRC and LoRa connectivity

Last year, Semtech released the LR2021 LoRa Plus transceiver chip, designed to address the low data-rate issue associated with LoRa, but surprisingly, they didn’t release a development board for the chip. Now, almost a year later, Seeed Studio and Semtech have partnered to introduce the LR2021 LoRa Plus development kit targeting long-range high-speed LoRa and FLRC applications up to 2.6 Mbps. Not only does the board support LoRa Gen 4 technology, providing Sub-GHz, 2.4 GHz ISM, and S/L-band operation, but a XIAO nRF54L15 board also adds dual-core processing (Arm Cortex-M33 + RISC-V) and supports other short-range protocols, including NFC, Bluetooth LE 6.0, Matter, Thread, and 2.4 GHz proprietary protocols. The development board also features a 0.96-inch 128×64 OLED, three Grove connectors for expansion, a USB Type-C for power, SWD debugging, and two Sub-GHz and 2.4 GHz SMA connectors. It is compatible with Arduino Uno, STM32 Nucleo, and Nordic DK boards. […]

SlimeVR Butterfly Trackers – nRF52833-based, ultra-slim, full-body VR trackers offer up to 48h battery life (Crowdfunding)

Designed by SlimeVR in Rotterdam, Netherlands, the SlimeVR Butterfly Trackers are open-hardware, IMU-based, ultra-slim, full-body VR trackers designed for virtual reality gaming, motion capture, VTubing, and more. The trackers provide full-body positional tracking without base stations, cameras, Wi-Fi, or Bluetooth. Each tracker uses an IMU to measure absolute rotation and transmits data over a custom 2.4 GHz ESB protocol via a dedicated dongle supporting up to 10 trackers, eliminating occlusion issues and router setup. Based on Nordic Semi’s nRF52833 wireless MCU, the split “butterfly” design places the PCB and 90 mAh battery side-by-side to achieve a thickness of under 7 mm and a weight below 10 grams, while a flexible interconnect improves comfort when worn under clothing. The system offers a 100–200 Hz refresh rate, <15 ms latency, over 48 hours of battery life with USB-C charging and OTA firmware updates. SlimeVR Butterfly Trackers specifications: Wireless MCU – Nordic nRF52833 CPU […]

ESP32 Marauder 5G – Apex 5 module for Flipper Zero combines ESP32-C5, two Sub-GHz radios, nRF24, and GPS

Designed by HoneyHoneyTrading, the ESP32 Marauder 5G – Apex 5 Module is an ESP32-C5-based hacking and penetration testing tool for the Flipper Zero, with dual-band WiFi 6 (2.4GHz and 5GHz), two Sub-GHz radios (868MHz and 433MHz), an NRF24 radio, and a built-in GPS. This new Flipper Zero module can be considered an upgrade from the ESP32 Marauder – Double Barrel 5G, as it does not rely on a dual-chip configuration for 5 GHz operation, leveraging the ESP32-C5 dual-band capabilities instead. A microSD card slot handles storage, and the device can also save data directly to the Flipper Zero’s microSD card. It also features five antennas, including WiFi, Sub-GHz, nRF24, and GPS, along with dedicated LED indicators for the Sub-GHz radios and nRF24 activity. There is also a hardware button to toggle 433 MHz and 868 MHz Sub-GHz operation, a USB-C port, and a side button for power management and firmware […]
