MR ROTJ + Polalu +Recharge

[Whi-ja]

Hello, all!

I'm sitting here staring at a 2007 Luke MR ROTJ board, a Pololu LV momentary-to-latching circuit, 18650 3.7V battery, and a TCSS recharge port, and momentary tactile switch... (as well as other accoutrements that don't apply to the problem at hand, such as the speaker, LED, etc.)

I've used the recharge ports before. I've used the Pololu before. Now I want to use them together with the MR board for a concept saber (a "rough draft build" of the hilt, if you will), but for some reason I hesitate, and so I'm asking for a wiring check before I proceed.... Which wire goes to the "GND" pad on the Pololu? The tutorial pic makes it look as though the GND pad on the MR board should have two leads from the same pad, one of which goes to the Polou board, and the other of which leads to the battery, or in this case the appropriate post on the recharge port.

Seems easy enough. Am I just having a case of the jitters, or is there a reason the danger sense is pinging in my head?

I think it's just nerves, but this is how I see it laying out, and it makes sense, but I (dare I say it) "have a bad feeling about this" and just need someone to confirm that I'm not crazy before I burn out a board (It's been almost a year since that last happened, and I'd hate to start again now!)

I really appreciate this forum and this community; thanks in advance for help with this question... This is what I've got:

I used a set up very similar to that and yes that is what my wiring diagram would have looked like if I had bothered to make one :P

you are on the right track with that

Thank you. I don't know what gave me pause. It's too easy, but I just needed to be sure I guess.

I had to fiddle with mine before i got it to work right
