Hexapod build - question about solderless relay connection to the servo controller 2040 board

Hi , I am building hexapod and using beneath wire diagram. As I am new to making it I would like to ask if it is possible to connect relay to the sc2040 board without soldering it [just in case if I change my mind about it …] I am planning to use Gravity: Digital Relay Module (Arduino and Raspberry Pi Compatible).

note: I will be using raspberry pi instead of android phone

You could solder a strip of header pins to that side of the board and then connect using matching Dupont wires to connect to the relay. That would simplify any future changes.

A different option is to have the gear needed to remove soldered connections. This has the advantage of removing press-fit connections as a potential source of intermittent problems. To do this the following items would be useful:
