Connecting device using SPI (i.e.LoRA)

[ivicajan]

Dear developers, I would like to add a loRA shield to the T-A7670E and to do that I need standard sets of pins to connect to. Overall, the project is aiming to collect the data using a loRA shield, store them on an SD card, use GPS location/time, and upload packages via SIM card modem to the server.

What would you suggest which pins could be used on the board that are not already taken? In particular, I would need something like this (but pins that I can use):

define pin_ss 5

define pin_rst 32

define pin_dio0 34

define pin_dio1 39

define pin_mosi 23

define pin_miso 19

define pin_sck 18

Thanks in advance!
