A WIZ750SR based device that allows sending and receiving messages over LoRa and LoRaWAN.
I got some LoRa modules with SPI communication interface. One of the options it would have been to connect them to my Raspberry Pi. But, I didn’t really like the idea because I already have some stuff connected to my Raspberry Pi, and this starts getting unmanageable.
So, I decided to create a LoRa-to-Ethernet gateway that I can connect directly to home router. The WIZ750SR module with its Ethernet interface and Cortex-M0 SoC it’s a great candidate for this.
Murata produces LoRa module CMWX1ZZABZ-xxx based on SX1276 transceiver and STM32L072CZ microcontroller. The soldering of the LGA module is not very hobby-friendly. I constructed small breakout PCB for this module with additional buck/boost switcher and place for SMA connector. The transceiver features the LoRa®long-range modem, providing ultra-long-range spread spectrum communication and high interference immunity, minimizing current consumption. Since CMWX1ZZABZ-091 is an “open” module, it is possible to access all STM32L072 peripherals such as ADC, 16-bit timer, LP-UART, I2C, SPI and USB 2.0 FS (supporting BCD and LPM), which are not used internally by SX1276.
This is the third generation of our succesful SODAQ ONE board. It is equipped with a solar charge controller and runs on a LiPo or a permanent battery. It has the Ublox Eva 8M GPS module which is not only miniature but with it’s assisted GPS feature it can get a fix within seconds. We’ve now added an extremely low power Accelerometer/Magnetometer. This gives the board a nifty feature where it can stay in (deep) sleep mode until it moves. An essential feature for developing low power devices.
Let’s imagine you want to develop a bicycle tracker using the SODAQ ONE. You would like to track the position of the bike, but only when it has moved. This is possible if you keep the device in deep sleep until it detects motion. If the motion continues for a while, the bicycle may have changed position so only then the GPS will switch on to get a new reading and send this location over the LoRa network. Efficient right? This system will allow you make most efficient use of your battery capacity by only using the GPS when really needed, essentially increasing the battery life of your system.

An ultra low power LoRa sensor node powered by just one CR2032 batter. By Harm Wouter Snippe:
Do you want to measure temperature, connect a soil humidity sensor in your vegetable garden or monitor the air quality at your street corner? With the Fennec Development Board you are able to connect almost any sensor and create your own amazing ultra low power wireless projects. We have created the most energy efficient Arduino compatible IoT device with LoRa communication in the world. Powered by only a button cell you can send sensor readings every 15 minutes for the next five years over long distances (5-15km).
Based on the ESP8266 module, “Andres Sabas” unite the best of WiFi and LoRa, Facilitating the development of IoT solutions.
LoRaCatKitty is designed to simplify the development of Internet of Things (IoT) applications using the fabulous (but still underutilized) LoRa Technology. We have based our development on the ESP8266 WiFi module and the LoRa RN2903 or RN2483 microchip module, and we have designed it to allow you can create IoT applications without deep knowledge of technology.

The hardware startup Pycom have been working hard to create a fast-develop-and-connect hardware portfolio, a portal and gathered enough developer manpower to unleash the IoT growth potential. Pycom has just launched its newest product: FiPy!
FiPy is the new IoT module that connects your device to other networks. According to what the company describes, it is the most comprehensive solution, unifying LTE with other proprietary or unlicensed LPWA technologies into a single, five-network IoT connectivity solution.
“In addition to WiFi, BLE, LoRa and Sigfox, we’ve added the latest cellular technology for IoT: LTE-M. But, we didn’t just go for one frequency type either. Nope, we partnered with the leaders in their field, Sequans, and are now proud to confirm that our module will have both CAT NB1 and CAT M1.”
The board specifications
ESP32-based – Espressif ESP32 SoC
Dual processor and WiFi+Bluetooth radio system on chip
Supports 5 networks: WiFi, BLE, cellular LTE-CATM1/M2(NBIoT), LoRa, and Sigfox
Pycom is redefining IoT with this brand new module! FiPy gives access to all the world’s LPWAN networks on one tiny board. It is now live on Kickstarter, check the campaign video:
You can pre-order your FiPy now for $39, the campaign still has 23 days to go and it has already achieved double of its goal. More information about FiPy plus its sensors and accessories check the crowdfunding campaign and the official website.
The LoRa Alliance™ is an open, non-profit association of members who believe that the Internet of Things era is now, its LoRaWAN is a Low Power Wide Area Network with features that support low-cost, mobile, and secure bidirectional communication for Internet of Things (IoT), machine-to-machine (M2M), smart city, and industrial applications. LoRaWAN is optimized for low power consumption and is designed to support large networks with millions and millions of devices. Innovative features of LoRaWAN include support for redundant operation, geolocation, low-cost, and low-power – devices can even run on energy harvesting technologies enabling the mobility and ease of use of Internet of Things.
Check this video to learn more about LoRa and its protocol:
Badgerboard is an Arduino compatible LoRaWAN™ open source development kit, that can be easily extended to a prototype or even a small batch product. Development board has a battery charger and antenna connector on board.
Using as small as the battery you have in your watch, you can power your Badgerboard to send and receive radio waves, that can reach from 1km to 3km in the urban area up to 10+ km in the rural areas
The communication is powered by widely used Microchip LoRaWAN module. There are two editions of the module one using RN2483-I/RM101 for the 433/868 frequency bands and the other is using RN2903-I/RM095 for the 915 MHz band and its sub-bands. The LoRaWAN stack is already part of the module and all needed libraries for LoRa functionality are included.
Here are the features of the module:

Badgerboard is now live on a Kickstarter campaign, you can pre-order the early bird board for $45 here. You can check their website to keep involved with the latest updates www.badgerboard.io
Internet of Things became one of the most important technology trends nowadays, and everyday we have a new board or tool that helps people to create IoT application. Today, we introduce you to “Marvin”, a new IoT board developed at RDM Makerspace.
Marvin is an easy to use, plug and play development board for rapid prototyping of IoT solutions with a full size USB port. It is compatible with the open source Arduino platform and works with LoRa communication on LoRa networks.
The board is designed as a USB stick, so you can program it directly into your computer, and once you are done you can plug it into a power bank easily without having to bother with any cables in the process. Marvin is based on the Microchip RN2483 as a LoRa module with 868 & 434 MHz frequency bands, so you can use it anywhere outdoor in Netherlands, and other countries.
Marvin is also compatible with Grove System, modular, ready-to-use tool sets. Similar to LEGO, it takes a building block approach to assembling electronics. The Grove system consists of a base shield and various modules with standardized connectors. A wide range of Grove modules are available for use within the Grove System.
LoRa, stands for Long Range Low Power, appears to be one of the most popular LPWAN standards. It is a very efficient, light weight way of communicating small messages wireless. The LoRa module is a hardware chip, that is most of the time sleeping, which means you save loads of power.
Connectivity – LoRa via Microchip RN2483; Supports both 868 MHz and 433 MHz frequency bands, on-board antenna
USB – 1x USB, 1x micro USB port for power and programming
Debugging – USB, and ISP header
Expansion – 5x Grove connectors
Power Supply – 5V via USB port
Dimensions – N/A, but similar to USB flash drive
There are five steps to create an IoT project, first connect Marvin to your PC and add sensors, then write your code and upload it to Marvin, finally connect to the power source and enjoy testing your project.
The project has been recently launched on kickstarter, and the developers had surpassed their €10,000 funding target with close to €16,000 raised so far. Ordering Marvin is available for €70 through the campaign page with many other offers.
