$6 RAK3172 WisDuo LoRaWAN module features STMicro STM32WL LoRa SoC

RAK3172 WisDuo

RAK3172 WisDuo is a LoRaWAN module smaller than most coins with 15.5×15 mm dimensions made possible thanks to STMicro STM32WL Cortex-M4 LoRa SoC, which we previously found in Seeed Studio’s $10 LoRa-E5 module and corresponding development boards. But while Seeed Studio relies on STM32WLE5JC SoC with 256KB flash and 64KB RAM in a 73-pin UFBGA package, RAKwireless RAK3172 Wisduo is powered by STM32WLE5CC with the same amount of memory or storage, but in a  48-pin UFQFPN package, and an even lower price at just $5.99 in single units. RAK3172 Wisduo specifications: SoC – STMicro STM32WLE5CC55 Arm Cortex‐M4 MCU @ 48 MHz with 256 KB flash memory with ECC, 64 KB RAM, and a sub-GHz radio based on Semtech SX126x LoRaWAN 1.0.3 specification compliant Supported bands – EU433, CN470, IN865, EU868, AU915, US915, KR920, RU864, and AS923 LoRaWAN Activation by OTAA/ABP LoRa Point to Point (P2P) communication Range – Greater than […]

Check LoRaWAN deployments on the go with WisGate Developer Base USB dongle

Wisgate Developer Platform

RAKWireless just had their “Big Tech Bloom” event services they announced many new LPWAN products ranging from WisDM fleet management system, OpenWrt based Wisgate OS, new industrial LoRaWAN gateways like WisGate Edge Lite 2, their first STM32WL module, as well as 9 new modules for WisBlock modular IoT platform with MIC, e-Paper display, GPS, an ESP32 based WisBlock core, etc… But today, I’ll have a look at the new $99 WisGate Developer Base, a USB dongle that connects to a laptop for LoRaWAN networks evaluation, for example, to check the coverage before installing a new gateway. Alternatively, it could also be used to add LoRaWAN gateway capability to existing embedded hardware like routers or industrial PCs. Two variants of the WisGate Developer Base are available – RAK7271 & RAK7371 – with the following specifications: Concentrator modules RAK7271 – RAK2287 SX1302 based mini PCIe concentrator module RAK7371 – RAK5146 SX1303 based […]

Rakwireless Launches WisBlock IoT Modular System Beta Testing Program

WisBlock IoT Modular System Prototype

Rakwireless has launched several IoT evaluation boards such as RAK4260 LoRaWAN EVB relying on WisBlock modules comprised of a carrier board and a module. So far, those were always sold as part of evaluation boards, but now the company is trying to expand WisBlock use as a modular system, so users can easily build their custom systems, LEGO style. The modular system is based on four different block types: WisBlock Base – A carrier board with connectors for other block types, power supply, some ports WisBlock Core – Module with a microcontroller/processor WisBlock Sensor – Modules with environmental sensors, motion sensors, ambient light sensors, or others WisBlock IO – Adds more inputs, outputs, or connectivity options including  LTE-M / NB-IoT, cellular and Wi-Fi modules, NFC reader, and interfaces for I2C, UART, ADC, and GPIO.

RAK2287 Mini PCIe LoRaWAN Concentrator Module Supports up to 500 Nodes per km2

RAK2287 LPWAN Concentrator Module

RAK Wireless launched its first Mini PCIe LoRaWAN concentrator module in 2018 with RAK833 mPCIe card featuring Semtech SX1301 LoRa baseband chip. It was soon followed by RAK2247 mPCIe with a very similar design but some tweaks to increase its maximum transmission power and range, and improve thermals and stability with the addition of a heatsink. The company has now introduced a new version with RAK2287 Mini PCie LoRaWAN concentrator module being mostly inspired by RAK2247 module but replacing Semtech SX1301 by Semtech SX1302 LoRa transceiver that’s suppose to reduce current consumption (and heat), lower the BoM cost, and able to handle a higher amount of traffic. The new mini PCIe card also adds u-blox ZOE-M8Q GPS system-in-package to provide GNSS functionality. RAK2287 key features and specifications: LoRa Connectivity Semtech SX1302 LoRa Transceiver with 2x SX1250 Tx/Rx front-end Tx power – up to 27dBm Rx sensitivity – down to -139dBm […]
