Hello,
I am using the RAK4630 module and would like to confirm whether it can be powered directly using a 3.6V 19000mAh ER34615H + EPC1520 lithium primary battery pack.
If this is possible, does it mean that no external voltage regulator is required?
Kind regards,
Welcome back @fab ,
That is possible. You need can feed the 3.6V to the supply of nRF52 and SX1262.
There is a note on the schematic.
