Folks,

I have been having wonderful results with the TL-WR902AC powered by battery, and wanted to take the next step to bypass the 5V -> 3.3V down converter and power my TL-WR902AC with 3.3V

I am running into a curious problem, and wanted to get advice here

I have 2 wires soldered to the appropriate pins on the serial interface on the PCB.  When I power the extended via USB (5V), I read 3.3V on those wires (all good so far)

However, when I connect 3.3V power supply to those wires on the serial interface, my extender does not power up at all (nothing on LEDs, etc)

For those with version 4.x of the extender, has anyone successfully powered the extender with 3.3V to the serial interface?

Do I need to remove the 5V->3.3V regulator perhaps?

Any advice/leads appreciated (alas, I can’t trace leads on the PCB so difficult to debug)

Best wishes

Ray
