For a university study I'm trying to create a wearable device that gets some data from some sensors and send them to another device using BLE. I am using the DA14681 board (I don't know wich package, in the box it's written "DA14681-01DKWEAR") and I alredy wrote the program. Now I just need to solder the sensors to the board, but I can't seem to find the correspondance between the pins.

We alredy looked at the materials provided in this question:

but we cannot find the information we need

For example one sensor is connected to the Pins P4_4 and P1_2 of the development kit, but we cannot find to what pins we must solder it.
