The name is OK. I'm just worried about the voltage. We don't want users frying their display panel. They probably cost more than the board itself. For most of these SBCs, they are designed to work with the panels they provide. Could you reach out to TL Lim and ask about the voltage used? Or maybe dig it out of the FEX files?
