Hello
i have a brand new TTGO LoRa32 V2.1.6 (aka T3 V1.6, aka LoRa32 V2.1 release 1.6): (my is T3 v1.6.1 20210104)
i setup and work powerd over usb. But i havent the place to power it like that.

Hi.
Is this the board that you have: https://github.com/LilyGO/TTGO-LoRa32-V2.1?
I don’t have any of those boards to experiment with.
Do you have a multimeter to check if the power source is providing 5V?
Do you have any peripherals connected to the board?
I’m not sure if the 5V pin is input and output or just output. If it is just output, you won’t be able to provide power through that pin. It will help if you have the schematic wiring diagram of that board.
That board has a battery connector (in the image I’ve sent you, you can see the + and – signs). You probably need to use those to provide power (but I guess it is not proper for 5V).
Regards,
Sara

Her is the schematic: TTGO-LORA32/schematic1in6.pdf at master · LilyGO/TTGO-LORA32 · GitHub
Look at the +5 on the power page. Each one them feeds a 3.3 volt regulator.
