Nextion Displays – Current draw

Lowell has tested current draw on a 2.4″ and a 3.2″ Nextion display following questions from constructors over the likelihood of cooking the existing 5V regulator.  With a supply voltage of 5.04 VDC, the 2.4″ display drew 125 ma. and the 3.2″ display drew 110 ma. Both  displays were at full brightness.   While the figures are slightly above those listed on manufacturer’s website, this suggests the 5V regulator should be fine.   If in doubt, add a heatsink!
