Vems knock ec18 pinouts

[lost]

Hello, i have vems v3.5 (it should be same as 3.3) and want to connect knock chip with wires to ec 18 pin 1-2-3

I have noticed that i have some smd components near ec18 pins that v3.6 does not have installed.
and 3.6 has some components that i dont have. Is it possible to burn somethin if in that place is analog IN ?
