CubeCell HTCC-AB01 V2

Perhaps someone from Heltec could advise of what lcd displays are compatible with the HTCC-AB01 V2. I would like to attach either an ILI9341 or ST7789 lcd display to it.
If there are no lcds compatible I will discard them and move to a PRO mini which seems to work with most lcd drivers. The sales information says the
Heltec module is fully Arduino compatible. In my experience this is far from the truth.
