I am a novice want to add a number module function to my board, please do what I how to start, there is a master willing to help me add a number module function

The following is my PCB format design drawing

If you have the PCB, then it should not be difficult for you to trace out a schematic.

Thank you, teacher.

Obviously it is some kind of PI detector.
But the unusual pcb design, the unusual way of drawing the connections as well as the DC connector...?
Is this a regular PI detector or for some other purpose?

Is ordinary PI, two separate boards, similar to the dbp2010 structure, depth 3-4 meters, using 2 × 2 meters square coil, very unstable in the mineralized area I want to add a digital programming chip for him, I have no clue
