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. DINGO-LORAWAN-GW_SVR-01 key features and specifications: System-on-Module – Raspberry Pi Compute Module 3+ with Broadcom BCM2837B0 quad-c ore Arm Cortex-A53 processor @ 1.2GHz, 1GB LPDDR2 RAM, 8GB eMMC Flash (16GB or 32 GB as option), RTC Info Display – 128×64 pixel OLED LCD Video Output – HDMI Networking 1x RJ45 10/100BaseT Ethernet 1x RJ45 10BaseT Ethernet LoRaWAN connectivity Support for LoRaWAN V1.0.2 and V1.0.3 Tx Power – Up to […]

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

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 […]

Feather compatible shield Integrates BG96 Module with LTE Cat-M1, NB-IoT, and GPS

Last week, I wrote about the Pebble Board, an nRF9160 based LTE-M and NB-IoT GPS tracker board that connects with Thingsboard. I was soon informed about a similar solution based on Quectel BG96 and compatible with the Feather form factor. Meet IoT-Bots.com’s qTop Adafruit Feather Compatible shield. In case you wonder, why they did not call it a FeatherWing, that’s because as it’s slightly larger, and the boards are “Adafruit Feather Compatible (AFC) from the interface connection perspective only.” Key features and specifications: Wireless module – Quectel BG96 Cellular – LTE Cat M1, NB-IoT, and EGPRS module offering maximum data rates of 375 kbps downlink and uplink GNSS – GPS, GLONASS, BeiDou/Compass, Galileo, QZSS Nano SIM card holder and u.FL connector (3) for cellular connectivity u.FL connector (4) for GNSS Expansion Feather expansion connector (11) 6-pin qJam interface connector (12) with I2C for extra sensors Misc – Network status LED, […]

Pebble Tracker nRF9160 GPS & cellular IoT platform connects to IoTeX blockchain (Crowdfunding)

Nordic Semi nRF91-series of Cortex-M33 SoCs with NB-IoT and LTE-M (eMTC) cellular IoT connectivity was first unveiled in 2018. The first member of the family is nRF9160 System-in-Package (SiP) which also comes with GPS, and we’ve found it Nordic’s own Thingy:91 devkit, as well as in various modules and development boards from third parties. There’s now a new kit called Pebble Tracker that features Nordic Semi nRF9160 with NB-IoT, LTE-M, and GPS connectivity, as well as environmental, motion, and light sensors. The cellular IoT prototyping platform works with the IoTeX blockchain to design decentralized IoT solutions with higher security.

LoRa 2.4GHz is now supported by The Things Network

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 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 […]
