Reference nRF52840 pcb schematics and layouts are exactly the same for examples 2-6. I believe each is a copy of var4. The schematics for these reference designs are listed correctly in the specification document but do not match what is included here.

shas for the files mentioned:

Here's a link to the related section on infocenter:
https://infocenter.nordicsemi.com/topic/ps_nrf52840/ref_circuitry.html?cp=3_0_0_6_2

It would also be nice if Nordic had a permanent link scheme for infocenter. I can't tell you how many links I've encountered referenced in devzone and elsewhere that are broken.
