Core1121 sub-GHz, S-Band, and 2.4GHz LoRa module features through holes and castellated edges

The Waveshare Core1121 is a compact, multi-band LoRa module based on the Semtech LR1121 transceiver with support for Sub-GHz (150–960MHz), S-band (1.9–2.1GHz), and 2.4GHz ISM bands, and exposing GPIOs through both through and castellated holes. Key features include support for LoRa, (G)FSK, and LR-FHSS modulation schemes, AES-128 encryption, and compatibility with the SX126X/SX127X series for easy migration. We just noted Seeed Studio’s Wio-LR1121 last week with a very similar, yet more compact design with only castellated holes, and before that, the LR1121 was used in the MuRata Type-2GT module and a LILYGO module as an option for the T-Eth Elite board. Core1121 specifications: RF Transceiver – Semtech LR1121 Frequency bands Sub-GHz (150MHz ~ 960MHz), Different varieties for Europe, North America, Oceania, Asia S-band (1.9GHz ~ 2.1GHz) 2.4GHz ISM frequency bands Output Power Up to 22dBm @ 868/915 MHz (Sub-GHz) Up to 13dBm max @ 2.4GHz Receiver Sensitivity -127dBm @ Sub-GHz, SF7, CR4/5, […]

Wio-LR1121 tiny LoRa module supports for sub-GHz, S-Band, and 2.4GHz frequency bands

Seeed Studio Wio-LR1121 is a tiny, multi-band LoRa module based on LR1121 RF transceiver, a low-cost version of LR1120 without GNSS or Wi-Fi scanning capabilities, that supports sub-GHz, S-Band (1.9-2.1GHz), and 2.4GHz frequency bands. We had previously seen the LR1121 used in the MuRata Type-2GT module and a LILYGO module as an option for the T-Eth Elite board. The Wio-LR1121 offers another option that’s easy to solder, thanks to castellated holes and pads. Wio-LR1121 specifications: RF Transceiver – Semtech LR1121 Frequency bands – 863 to 928MHz and 2.4 to 2.5GHz frequencies; Note: The LR1121 also supports S-Band at 2.1 to 2.3 GHz, but it’s not mentioned in the specifications of the module, and only briefly in the title and description Output Power Up to 20.4dBm @ 868/915 MHz Up to 11dBm max @ 2.4GHz Receiver Sensitivity RxBoost ON： -126dBm @ SubG,BW=125KHz, SF = 7 -140dBm @ SubG, BW=125KHz, SF = […]

WisMesh Board ONE allows you to build a custom Meshtastic Node with OLED, GPS, battery, enclosure, and more

There are now plenty of Meshtastic hardware platforms for off-grid messaging, audio communication, and GPS coordinate sharing, be it boards or modules for DIY projects, or complete solutions with battery and enclosure working out of the box, such as the Wio Tracker L1 Pro or ThinkNode M2, among many others. In some ways, RAKwireless’ WisMesh Board ONE baseboard offers the best of both worlds, combining the flexibility of DIY designs with the convenience of complete solutions, as it allows users to create a custom Meshtastic node with optional OLED, GPS, battery, antennas, and enclosure besides the usual choice between 868 MHz and 915 MHz LoRa radios. WisMesh Board ONE specifications: Wisblock RAK4631 Module pre-flashed with the Meshtastic firmware SoC – Nordic Semi nRF52840 Core – 32-bit Arm Cortex-M4F CPU @ 64 MHz Memory – 256 KB SRAM Storage – 1 MB Flash Wireless – Bluetooth LE LoRa Transceiver – Semtech […]

RAKwireless Raspberry Pi CM4-based industrial gateway supports both MIOTY and LoRaWAN

WisGate Connect for MIOTY LoRaWAN gateway

The WisGate Connect for MIOTY is an industrial-grade hybrid IoT gateway with support for both MIOTY and LoRaWAN protocols. Built around the RAK7391 carrier board for Raspberry Pi CM4, it is designed for long-range IoT applications, including intelligent street lighting, waste management, environmental monitoring, and traffic flow control. In addition to dual-protocol (MIOTY and LoRaWAN) support, it features USB 2.0, USB 3.0, and a USB-C port for flashing, an HDMI output, and a UART header for debugging. Backhaul options include Wi-Fi, Ethernet, or an optional 4G LTE module. The gateway can be powered in two ways: a wide input voltage DC jack or terminal block, or optional PoE+. We first wrote about the MIOTY Standard back in April 2020. After that, in September 2021, we saw Silicon Labs introduce EFR32FG23 (FG23) and EFR32ZG23 (ZG23) SoCs with MIOTY support, but it’s been a while since we’ve covered products built around this standard.

The Future of Asset Tracking: IoT at Scale with LTE-M technology

CNXSoft: This is a guest post by Ohad Peled, Product Marketing Manager at Sony Semiconductor Israel, about the challenges of tracking a large number of IoT assets and how LTE-M can help businesses scale tracking solutions. Over the last few years, asset tracking has emerged as a critical business function and is estimated to grow to a $34.5B market by 2032, according to Custom Market Insights. Whether businesses are monitoring a global supply chain or keeping tabs on expensive equipment, knowing where assets are at all times is essential. It enables businesses to optimize supply chains, prevent theft, and reduce operational downtime. There are several technical and commercial challenges in deploying such a solution, which could result in failure to deliver the promised value. Some solutions struggle to maintain accurate tracking as assets move within or across different facilities, especially if they go through an indoor environment. Others suffer from […]
