I am afraid that I do not know which PA Estimote is using in their design and if I knew I would not be able to disclose it :) It will depend on which PA you select, but with the SKY66111-11 you're looking at an additional 10mA. You usually configure the nRF52832 to transmit at 0dBm, which will typically be 5.3mA, so the total is then around 15mA.

Thanks for the quick answer!

Any idea which amplifier estimate are using? What is the likely power impact of adding such an amplifier to the application?

Hi Jumpingfool,

it is possible to add an external Power Amplifier(PA) to increase the output power from +4dBm to +10dBm.

Best regards
