when I set the nextion to sleep mode, it still consume 17mA which is too high for sleep mode.
is there is a way to make the module consume less power during sleep?
I am now reviewing all of the Feature Requests, this will take some time, patience please.
5V input is needed to drive the LED display, MCU draws 3.3V post regulator.
3.3V pads for factory loading of firmware and testing (serial wire debug)
Powering display with 3.3V through pads will damage eventually the LED portion of the display, under powered
Although this wasn't a real feature request, it is now marked as reviewed.
so which Resistor is connected to the LED? so I can change it to match 3.3V instead of 5V
No. Nextion display is powered by 5V.
Anything less will damage the screen.
Rx/Tx can be 3.3V but display requires 5V
