Hi, did you manage to fix this? I'm facing similar problems with board definitions, although the board I'm using is probably a different version, it's a Lora32 but on the back it says T3 V1.6.1.
I'm probably doing something wrong, but it either gives an error about header file missing in libraries (Xinyuan-LilyGO), wrong pin definitions (Sandeepmistry), etc.
Since this is a very common board I'm hoping you or someone else can point me to the correct library.
Thanks!
