A nice, but not essential enhancement
Functionally, this module is just an on/off switch. But besides allowing you to switch off the power at the board, you can remove the power cable, which could make transporting the board a little easier. Supposedly, there is noise filtration as well, although if this contributes to the price, I wish they had left it out. Installing these is a bit delicate, so make sure you remove the end plate of the board first.
