Seems like good all-in-one solution for SoftRF + SkyView and it has big AMOLED display and I am a fun of AMOLED displays in aviation. Then I read that it only supports ESP-IDF framework and was a bit disappointed.
Turns out the upstream SoftRF version 1.8 supports
T-Display P4 if I understood it correctly from the Commit messages (nothing on the website yet)
Unfortunately, those devices re sold out till end of January, I would be interested to get one and try.
Understandably, it will need work done to port SkyView features across, but that should be nice project.
