First of all, thanks for the great project!

I would like to know which HW version of LilyGO T-RGB device I need to order to reproduce your bike computer.

On LilyGO I have seen at least three HW-version:

2.1 inches Half Circle (Touch Chip: FT3267)
2.1 inches Full Circle (Touch Chip: CST820)
2.8 Inches Full Circle (Touch Chip: GT911)

I tried to find any mention of these ICs in sources, but I have failed.

Both 2.1" variants are supported:

You can set the variant in platformio.ini, by defining TRGB_OVAL or TRGB_ROUND:

build_flags =
    -DTRGB_ROUND
    -DBOARD_HAS_PSRAM
[....]

The changes to support 2,8" (GT911) should also be quite easy to implement, because the only difference is the touch chip.
