Btt tft70

I have a TFT 70 and skr pro/ tmc2209 coming that I ordered from Ali. I screwed up by placing it in 2 orders and not making sure they were coming from the same seller. So my screen is arriving this week but the board and drivers are still 2 months out.

Is there anyway I can power up the screen and play with changing buttons and stuff to cnc without having the board power it?

Thanks guys

i dont see why not, just need a power source, since there is a separate firmware.
I could be wrong though.
