Powering RAK4630 through 3.6V 19000mAh Er34615h Plus EPC1520 Lithium Primary Battery Pack

[fab]

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.
