nRF52840 Dongle TX Power +8 dBm with external regulated source

[Ferit]

Hi,

When I power nRF52840 Dongle from USB or VBUS pin with 5V, the TX Power is +8 dBm.

However, when I power the dongle from VDDOUT pin with regulated 3.3V, cut SB2 and solder SB1. I get a lower TX Power.

How can I set TXT Power to +8 dBm while powering the dongle from VDDOUT pin with regulated 3.3V?

Best Regards.

Hello,

''However, when I power the dongle from VDDOUT pin with regulated 3.3V, cut SB2 and solder SB1. I get a lower TX Power.'' How much TX power you got?
