Does anyone with more technical knowledge know whether this would work? I have an RGB saber powered by a Pico Crumble V1 and I want the option to customise my saber more. So if I add an Aux switch to my setup, is that the only change to my saber that I would need to make? From the looks of it, both boards use exactly the same recommended parts and so is it as simple as de-soldering the current connections, adding another switch and soldering it to the new board?
Here are the specs for my saber

LED: Tri CREE RGB XP-E2 LED
Red – Forward Voltage @ 1000mA = 2.6V
Green – Forward Voltage @ 1000mA = 3.1V
Royal Blue – Forward Voltage @ 1000mA = 3.1V

Battery: Xtar Protected 18650 battery 2600mAh 3.7V

Speaker: Veco 2W (3W max) 8 ohm bass speaker

Thanks for your time
