The Axon platform offers WiFi & LoRa IoT messaging in a compact form factor (Crowdfunding)

Axon Board

Qortex (Amine Mehdi Mansouri) has developed the WiFi & LoRa IoT messaging platform to allow devices to communicate wirelessly via serial messages. The solution also includes a wireless serial port and 4 digital outputs. The tiny Axon board is based on ESP8266 WiFi SoC and can be augmented with a LoRa module for a longer range, and the solution integrates with the Axon cloud for data visualization in the cloud. There’s also a HAT expansion board for Raspberry Pi compatibility.

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 mini PCIe concentrator module (New) 8 uplink channels and 1 […]

LoRaWAN BACnet gateway uses Raspberry Pi CM3+ for building automation

Raspberry Pi BACNet Gateway with LoRaWAN

A few years about we wrote about BASpi I/O Raspberry Pi HAT compatible with BACNet, a data communication protocol for Building Automation and Control Networks, also known as the ISO 16484-6  standard, and used for HVACs, lightings, elevators, fire safety, and other systems found in buildings. But if you’d like a turnkey BACnet solution based on Raspberry Pi, UK-based Innovelec‘s DINGO LoRaWAN BACnet Advanced Gateway/Server may be easier to integrate into your building’s electrical installation and also offers low-power long-range LoRaWAN communication.

$10 LoRa-E5 STM32WL module offers LoRaWAN networking in a 12x12mm package

LoRa-E5 STM32WL Module

Over the years, we’ve seen many LoRa modules combining STM32 microcontroller with Semtech SX12xx wireless transceivers, so that’s probably why STMicro decided to create the first LoRa SoC with STM32WL that was launched last year. I’ve just been informed a tiny (12x12mm) LoRa-E5 module based on STM32WL LoRa SoC working with 868 MHz and 915 MHz bands had recently launched on Seeed Studio for $9.90. LoRa-E5 key features and specifications: SoC – STMicro STM32WLE5JC Arm Cortex-M4 MCU @ 48 MHz with 256 KB flash memory, 64 KB SRAM, SX126x LoRa radio LoRa connectivity Tx power – 22dBm @ 868/915MHz -136.5dBm sensitivity for SF12 with 125KHz BW 158dB link budget Embedded LoRaWAN protocol, AT command Frequency ranges – EU868, US915, AU915, AS923, KR920, IN865 I/Os – 3x UART, 1x I2C, 1x 12-bit ADC, 1x SPIO Supply Voltage – 3.3V Power Consumption As low as 2.1uA sleep current in WOR mode Tx power consumption 50mA @ 10dBm (434MHz) 111mA @ 22dBm (470MHz […]

Deutsche Telekom IoT Gateway combines LoRaWAN and LTE-M

LoRaWAN LTE-M IoT Gateway

I’d normally view LoRaWAN and LTE IoT standards such as NB-IoT or LTE Cat-M (aka LTE-M or eMTC) as competitors, but The Things Industries and Deutsche Telekom​ partnered to launch an IoT gateway with both LTE-M and LoRaWAN capabilities together with associated services. We do not have much information about the hardware, but it is a LoRaWAN gateway designed by MikroTik that connects to an LTE-M backhaul and to The Things Industries’ device and data platform. If the picture above does indeed represent the actual gateway it should also be equipped with two PoE capable Ethernet ports, and an RS485 terminal block, plus a USB port and a SIM card slot. The solution would mostly be used for smart buildings at first taking advantage of the superior signal penetration of LTE-M. Sensors would send data to the LoRaWAN gateway which then, would forward it to the cloud over LTE-M. This type of solution could also be achieved through traditional LTE […]

LoRa 2.4GHz is now supported by The Things Network

LoRa 2.4 GHz

Semtech brought LoRa to 2.4 GHz through their SX1280 & SX1281 transceivers to enable hardware manufacturers to design region-independent products, rather than region-specific products in the 433, 868, and 915 MHz bands a few years back. Things Industries has announced support for LoRa 2.4GHz in The Things Network community network and its open-source stack at The Things Conference 2021 last week. However, switching to 2.4 GHz has a cost since range, one of the key selling points of LoRa, will be reduced compared to sub-GHz frequency, and that makes it most suitable for applications that work in different regions such as maritime and intercontinental logistics applications. Wilhelmsen has partnered with The Things Industries (TTI) and selected Semtech’s LoRa devices as the foundation for its new global 2.4GHz maritime IoT of the Seas platform to deliver an ecosystem of cost-effective, robust and proven IoT solutions and make them available to its diverse global customer base, at “land and sea”. Wilhelmsen can […]
