Inputs via GPIO on the Thingy:91

Hi,

I need to read a couple of external inputs - think buttons (although it's actually a sensor with relay output). It's for a prototype obviously.

I need to connect at least 1 but preferably 3 "buttons".

Preferably I'd like to solder the wires onto the board. Where would I preferably connect these? I haven't seen any schematics of the board.

Worst case scenario I'll just solder them onto the connector where the built-in button is currently placed - if it's the only option.
