T-display S3 Amoled touch 1.91" - use Lipo to also power other modules #73

Hi

I think I understood that I can use a lipo as a UPS in the case the 220V current of the usb-c power supply is missing. if I'm wrong correct me.

I would like to understand if I can use this system in some way to also power the SIM800L EVB module. (I don't think I can directly use the 5v pins of the T-display)

thanks best regards

The board cannot be used to directly power SIM800L. SIM800L requires at least 2A of power, and the board cannot provide such a large current. Only an external power supply can be used.
