This is part 19 of the LoRa/LoRaWAN tutorial.
In this video series different topics will be explained which will help you to understand LoRa/LoRaWAN.
It is recommended to watch each video sequentially as I may refer to certain LoRa/LoRaWAN topics explained earlier.
In this video I will explain which LoRa end node products are available today and how you can build your own LoRa development board.
All LoRa end nodes must have a microcontroller (e.g. ATMega32), a LoRa radio module (e.g. SX1276) and an antenna.
There are many LoRa end node products available, such as:
LoRa development boards where the microcontroller and the LoRa radio module are integrated on a printed circuit board (PCB).
LoRa radio shields, to be used for example with an Arduino board.
LoRa breakout boards. The LoRa radio module is mounted on a adapter plate.
LoRa radio modules.
For educational purpose I have build my own LoRa development board.
LoRa radio module + adapter plate + coil antenna. Total cost: € 8.07

Based on this self build LoRa development board, I will explain in the next video’s:
Which LoRa end node library to install on the Arduino board and how to configure it.
How to register this LoRa end node on The Things Network.
How to install a temperature and humidity sensor (DHT-11) on this development board.
Please note: I assume you have access to a LoRa gateway.
