Hi!
I am currently using a LILYGO TTGO T-BEAM v1.1 with PlatformIO and is getting the TBeam pins.
I checked for the schematics of this board and the builtin led should be 4 and not 14.

After some research, I have found that the TBeam pins are related to the LILYGO TTGO T-BEAM V0_7.
All pins for LILYGO TTGO T-BEAM boards here.

Maybe would it be a good idea to create another TBeam pins for the LILYGO TTGO T-BEAM V1 and 1.1 (which have the same pins configuration)?.

Thanks for the help and sorry if I am doing something wrong!
