user84630: I'm having issues stacking shields on my Arduino Mega 2560. I would like to add to the mega a ethernet shield (https://store.arduino.cc/products/arduino-ethernet-shield-2) and on top of that the dragino lora shield v1.4 (https://wiki.dragino.com/index.php?title=Lora_Shield). When I connect only the dragino lora shield to the mega I do get the lora to initialize but the moment I add the ethernet shield to the mega and the dragino lora shield to the ethernet shield the lora initialization fails. Is this stacking possible and if so any advice on how to get all to work together?
Thanks in advance.

user4143: Both those boards use pin 10 for chip select by default. You will need to change that.
Probably the simplest one to change is the LoRa board. If you look at the WiKi page you link to it lists a set of resistors and jumpers which can be altered to modify the connectivity of the board.  By default R9 is populated which connects to pin 10. If you move that to the R10 position next to it you will instead be connecting to D5 for the chip select pin. Moving surface mount resistors can be tricky though so you may want to practice working on a scrap board first.
And of course when you have changed the chip select pin you will also have to change your code to use that new chip select pin instead.
