https://devzone.nordicsemi.com/f/nordic-q-a/41076/pcb-migration-nrf52832-to-nrf52840Hi, We used nrf52832 in our custom pcb. It works. NRF52840 has &quot;Long Range&quot; feature. We think, if long range needs in some application, we can set 8dBm output power and otherwise we continue to use 4dBm like nrf52832. Is there sth. missing in thisen-USTelligent Community 13Mon, 03 Dec 2018 09:27:11 GMThttps://devzone.nordicsemi.com/thread/159910?ContentTypeID=1Mon, 03 Dec 2018 09:27:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e0ebd8c3-a1b4-4991-bc74-d28d405c409eSigurd<p>Hi,</p> [quote user=""]NRF52840&nbsp;has &quot;Long Range&quot; feature.
