With the 16x2 display the LM7805 was warm. Upgrade to a sexy 4.3 Nextion and the LM7805 was all nuclear core.?
Still. I suspect it would have served and suffered in silence for years and years.
Still. I put a heat sink and then moved the Nextion load to a off board buck converter.? Necessary? Not likely. Fun? Oh so much. Note I hacksawed part of the heat sink so it would not meld with the nearby toroid.
Much happiness and tropical temperatures in uBITX land.
