RAKWireless Introduces RAK7200 LoRa Tracker | Features & Specifications

RAK7200

RAK7200 is a LoRa Tracker node built around the AcSIP S76G chip. It integrates the ultra-low-power STM32L073 micro-controller, the SX1276 LoRa long range modem, and the CXD5603GF GPS receiver. The RAK7200, being a fully functioning LoRaWAN device, is particularly suited for IoT applications. Such as asset tracking, smart vehicle management, location-based service, etc. According to the device manufacturers, RAKWireless, a leading Chinese IoT solutions company, based in Shenzhen, RAK7200 requires minimal setup. Just pop in the included battery, close the housing and you can start sensing your GPS data over LoRaWAN. Furthermore, there are sensors built-into the board: a 9-axis accelerometer and pressure sensor. The new GPS Tracker node is an upgrade over the company’s earlier offering in the GPS tracker space, the RAK7205. Now, the earlier version, the RAK7205, was mostly aimed at developers, with its larger more robust casing and solar panel. But the RA7200 is more of a ready to use offering. It is more compact and …

easySwitchBox is a LoRa Wall Switch Powered by Coin Cell Batteries and Arduino (Crowdfunding)

easySwitchBox is a simple actuator that does one basic thing – To send an on/off signals that can be used to control anything wirelessly. Whatever you intend on doing with the signal sent is left to you.  easySwitchBox is the brainchild of easySensors, the Belarus based creators of DIY Arduino focused hardware products. easySwtichBox combines an Arduino based chip and a LoRa radio to be able to send a signal for long-range distances. On the surface, easySwitchBox looks like another wall switch you have seen around, but there is more to it. Powered by the famous Atmega 328P microcontroller, easySwitchBox is more than a wall switch, and you can reprogram it to be an intelligent one indeed or anything else you want. The power supply comes from two attached coin cell battery, making it possible to move the device around and not be confined by location or space. easySwitchBox is Arduino IDE Compatible, and you can re-upload a new …

N-Fuse Launches Raspberry Pi 3B+ LoRaWAN Gateway with PoE Support

PoE enabled Raspberry Pi 3B+ based LoRaWAN™ Gateway

Raspberry Pi is everywhere, and this small size single-board computer has reshaped technology and STEM education. The launch of the recent Raspberry Pi 4 is evident in the success and continuous growth. The Raspberry Pi 3B+ has seen so much success in several maker’s projects, while not the most powerful SBC in the market, but undoubtedly one of the most popular. I once put together an AI-powered mobile robot using just a Raspberry Pi 3B+, an RPLidar A2, and Raspberry Camera which was way capable of so many things. Another exciting Raspberry Pi end product is the “PoE enabled Raspberry Pi 3B+ based LoRaWAN Gateway” from n-fuse. The PoE enabled Raspberry Pi 3B+ based LoRaWAN Gateway as called by n-fuse is a LoRaWAN gateway based on the Raspberry Pi 3B+, the LRWCCx-MPCIE Concentrator, and the SBCPoE RPI Hat. It supports both the Europe 868Mhz and America 915Mhz frequency (you have to purchase the exact frequency you want though) The SBCPoE …
