nRF52840 alternative solution

[masterLee]

Hi, 

I have developed a project of mine based on the nRF52840 DK and now I want to place

the nRF52840 chip on my custom 2 layer PCB board but I think that it might be very difficult

when it comes to soldering. So my question is, if the nRF52820 chip would be a solution...

OK, I know the memory and GPIO limitations of the nRF52820 but I can solder it much more easily

I read that softdevice s140 can be used with nRF52820 without issues but what about the rest of the nrf52 SDK

Is it compatible with the nRF52840 configuration?

Any ideas?

Thank you for your time
