I want to use the LoRa-Technology to send hourly means of sensor measurements from my node to TTN. My Mega will be packed with sensors and other elements (GPS module, SD card module). I also have to use the SPI pins on my Mega for a micro sd card module.
The picture below kinda illustrates my issue. The sketch isn’t completely finished yet though. I want to put some more sensors into my setup, which I have to connect to the analog pins of the Mega. I also need a GPS module for my project, which I will connect through I2C to my Mega (Is there possibly a LoRa Module, which comes with a GPS module too?).
I’ve checked the following page: https://www.thethingsnetwork.org/docs/devices/arduino/usage.html
I guess I need a LoRa-Module with RN2483 or RN2903 to make use of the remaining RX1 pin and TX1 pin on my Mega to send my data using LoRa? I’m open for any advice or other possible options using LoRa!
