I want to mount a power switch on the front of my enclosure to power the VIM3 on and off. Should I solder the wires for the external power switch to the XPWR pads on the back of the VIM3? Or should I drill a hole in the XPWR pads and use POGO pins?
Also, what type of power switch should I use? A simple on/off SPST or a momentary switch?
Yes, pads can lift from PCB and other PCB damage can result from too much heat with the iron. Depending on ones soldering skills or experience, it could be risky. And sometimes I want to keep a device unmodified, once you tin the pads, be hard to get them back to shinny.
Making a POGO board is a better solution IMO and easier to undo if you re-purpose the VIM3 later. Of course it takes a bit more effort.
I look forward to your POGO board design.
Nice @Electr1. I am researching pogo/board options. “XPWR pads” seem proprietary. As someone mentioned previously, It looks like a pogo pad so maybe I can 3D print and mount a tiny board above that area of the Vim3. ¯_(ツ)_/¯
OK so I really need an alternative. I mounted a 2-pin connector and it worked but it was unstable. So, I tried my hand at soldering that connector to the board. Well, My poor attempt at soldering nearly destroyed the VIM. Is there a way to do this via GPIO (Programming or otherwise)?
