Arduino Shield for CAT M1 and NB-IoT Modems

LTE CAT M1 (sometimes called LTE-M) and NB-IoT are both exciting new cellular technologies targeting IoT applications. While there are many modems being built with this new technology, there are not many choices for hobbyists. There are a few Arduino shields and...

LoRaWAN Networking Part 2: Using End Devices

In part 1 of this series I showed how to set up a simple LoRaWAN gateway, and in a previous article described a simple but powerful LoRaWAN-capable end device that I designed. Now I’ll show how these devices can be used in a real LoRaWAN application. LoRaWAN...

LoRaWAN Networking Part 1: The Gateway

I have been playing with LoRa modules a lot recently (see projects LoRa Weather Station and LoRa Mesh Networking) and even designed my own LoRa development boards. LoRa is an easy way to achieve low-power, long range radio communication with small payloads. To get...

SAMD21 LoRa Development Board with GPS

Project source code at GitHub: samd21-lora-gps I’ve been doing some LoRa projects lately in order to learn as much as I can about this exciting new radio technology (see this LoRa mesh networking project and this LoRa weather station). ATmega328-based Moteino...

LoRa Mesh Networking with Simple Arduino-Based Modules

Project source code at GitHub: lora-mesh In this project, I will show you how I built a mesh network of 4 Arduino-Based LoRa modules and devised a way to visualize the network’s behavior in realtime. Using a realtime visualization we can see how the network...

Wi-Fi Camera Trap

Project source code at GitHub: wifi-camera-trap We have lots of small wildlife around our house (mostly rabbits this year) and since I have a small camera module and a cheap PIR (passive infrared) motion sensor, I thought it would be fun to make a motion triggered...
