Arduino “launches” WisGate Edge LoRaWAN gateways in collaboration with RAKwireless

Arduino was already involved in LoRaWAN with its MKR WAN 1300 board, but now the company has started offering Arduino-branded Wisgate Edge Pro and Wisgate Edge Lite 2 LoRaWAN gateways for respectively outdoor and indoor environments as part of the Arduino Pro family. If the names of the gateways seem familiar, it’s because Arduino collaborated with Rakwireless, and is simply using their existing LoRaWAN gateways. As I understand it RAKwireless will provide the hardware and technical support, while Arduino will sell the gateways and other LoRaWAN hardware through its existing customer base, more acting as a distributor. Arduino WisGate Edge Lite 2 indoor gateway specifications: SoC – MediaTek MT7628 MIPS processor @ 580 MHz System Memory – 128MB DDR2 Storage OS on flash SD card for setup and diagnostics, backup, and data logging Connectivity 10/100M Ethernet RJ45 port 2.4 WiFi (802.11b/g/n) with -95 dBm RX sensitivity, 20dBm Tx power; internal […]

ShaRPiKeebo handheld Linux computer based on Raspberry Pi Zero (2) W ships with a LoRa radio (Crowdfunding)

Raspberry Pi Zero portable Linux computer with LoRa

Morpheans ShaRPiKeebo is a portable Linux computer based on Raspberry Pi Zero W or Zero 2 W SBC that reminds me of the Allwinner R8 powered PocketCHIP handheld computer that was introduced in 2016, and was quite popular (for a niche product) at the time. The ShaRPiKeebo comes with a physical QWERTY keyboard, a daylight-readable screen, and Wi-Fi & Bluetooth connectivity, but also adds a 433 MHz LoRa radio that should make it usable as an off-the-grid communicator. Just like PocketCHIP, the ShaRPiKeebo can be used for system administration, retro-gaming, pen testing, STEM education, and all sort of maker projects. ShaRPiKeebo specifications: Supported SBCs via 40-pin GPIO header – Raspberry Pi Zero W, Raspberry Pi Zero 2 W, and (maybe) compatible SBCs like Radxa Zero or Banana Pi M2 Zero Display – 2.7- inch SHARP memory display (LS027B7DH01) with 400×240 resolution, low-latency, low-power Connectivity 802.11 b/g/n WiFi 4, Bluetooth 4.2 […]

Semtech LR1120 enables global asset tracking with multi-band LoRa, WiFi, and GNSS

Semtech LoRa Edge LR1120 is an ultra-low-power multi-band chip designed for global geolocation and asset tracking applications including direct satellite-connected Internet of Things (IoT) applications in supply chain management and logistics. Not only does the LR1120 features the usual sub-GHz LoRa radio found in most other chips from the company, but also comes with 2.4GHz LoRa and SATCOM S-Band support for satellite, as well as a GNNS radio compatible with GPS and Beidou, and a WiFi radio for indoor positioning (but no WiFi RTT/802.11mc support). Semtech LR1120 key features and specifications: Low-power high-sensitivity LoRa/(G)FSK half-duplex RF transceiver Worldwide ISM frequency bands support in the range 150 – 960MHz (Sub-GHz) and 2.4GHz, as well as 1.9-2.1GHz (S-Band) Low Noise Figure RX front-end High power PA path +22dBm in the Sub-GHz band Up to +11.5dBm in the 2.4GHz band LR-FHSS modulator Integrated PA regulator supply selector to simplify dual power +15/+22dBm with […]

RAKwireless adds more Wisduo and Wisblock modules, launches WisToolBox configuration tool for IoT devices

RAKwireless have launched several Wisduo wireless modules, a dozen of Wisblock modules for IoT prototyping, updated WisDM, WisGateOS, and RUI3 software, and introduced WisToolBox mobile/desktop configuration tool for IoT devices as part of their spring launch 2022 even entitled “Empowering the Innovators: Making IoT your own”. Three new Wisduo modules RAK3172-SIP WisDuo SIP based on STM32WLE5 Wireless SoC with LoRa connectivity. Compared to the original RAK3172, it offers more IO pins, integrates a TCXO, and comes in a smaller size. The module supports LoRa P2P and complies with Class A, B, & C of LoRaWAN 1.0.3 specifications. Cost: $5.99. WisDuo RAK3272-SiP – That’s a breakout board for the RAK3172-SiP System-in-a-Package module for LoRaWAN and allows easy access to all pins via 2.54mm pitch headers. RAK4630 WisDuo Stamp Module – This module supports both LoRa/LoRaWAN and BLE 5.0, and comes with RUI V3 (RUI3) firmware. It can be deployed as an […]

Ai-Thinker Ra-08 LoRaWAN module features ASR6601 chip (Sponsored)

Ai-Thinker Ra-08/08H are new LoRaWAN modules based on ASR Microelectronics ASR6601 module featuring a 48MHz ARM Cortex M4 microcontroller and Semtech SX1262 transceiver allowing long-range, low power communication for the Internet of Things. Both LoRaWAN modules share most of the same specifications, but the Ra-08 module operates in the 410-525MHz frequency band, while the Ra-08H module works in the widely used 803MHz to 930MHz band. Ai-Thinker also provides a development kit for each module.

Dragino LDS02 LoRaWAN door and window sensor offers long range and battery life

Dragino LDS02 LoRaWAN door & window sensor

Home automation usually relies on short-range wireless standards such as Bluetooth LE, Zigbee, or WiFi, sometimes with the help of repeaters for larger houses. But if you need to monitor large houses, several houses on a piece of land, or apartments, you’d be glad that you can also do so, at least for doors and windows, with LoRaWAN using Dragino LDS02 sensor. The LDS02 sensor will work like your typical wireless door/window sensor, detection when those are opened and closed, and for how long, but will offer a much longer range of up to 2km in urban settings, as well as battery life meaning it could last for years depending on the frequency of door/window events, as well as uplink frequency configuration. Dragino LDS02 LoRaWAN door sensor specifications: Based on SX1262 LoRa transceiver LoRaWAN v1.0.3 Class A Bands – CN470, EU433, KR920, US915, EU868, AS923, AU915, IN865 Door Open/Close detection […]

Challenger RP2040 LoRa board combines Raspberry Pi RP2040 MCU with RFM95W LoRa module

Invector Labs is now offering a variant of the WiFi-based Challenger RP2040 board with a LoRa radio. The Challenger RP2040 LoRa board features the Hope RF RFM95W LoRa radio transceiver module instead of the ESP8285 WiFi chip found in the original board. Raspberry Pi RP2040 has already been used in combination with a LoRa module, notably in Rakwireless RAK11300 WisDuo LPWAN module and the “LoRa Expansion for Pico“, a baseboard for Raspberry Pi Pico equipped with a LoRa module, but it’s the first time I see the combination in a development board form factor, which as a potential bonus following Adafruit Feather form factor. Challenger RP2040 LoRa board preliminary specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133MHz with 264KB SRAM Storage – 8MB flash Wireless module – Hope RF RFM95W connected via SPI channel and some GPIOs 168 dB maximum link budget. +20 dBm – 100 mW […]
