Custom boards based on LoRa-E5 and RAK3172

At 14dBm it should have a consumption of 45mA and it has 90mA because FW does not take into account the design choice of RFO_HP

Was aware of that.

However mintenj mentioned:

It would only be 23.5mA if the RAK3172 could connect the LP PA rather than the HP PA.

Which the RAK3172 cannot because they don’t provide LP PA on the module.

@Charles

the design choice of RFO_HP only (which by the way is a smart idea to reduce BOM and PCB size)

For BOM and PCB size this may be smart but if this means using 45.5 mA instead of 23.5 mA that would be possible if it would have supplied LP PA (RFO_LP or whatever its exact name) that means it uses twice as much power (45.5 mA) than what would have been possible with the STM32WLE55 chip. From battery operation perspective that would be a design flaw because using some 100% more power than necessary (if I understand correctly).
