Hey folks,

I'm currently putting together a circuit sword lite. I've tested it and got everything working perfectly (although I managed to break the black bit on the ribbon cable connector I managed to sort that out with some superglue).

I want to connect the rear button board (just L1 and R1) but I'm a little confused as to what goes where. I found a little connector on the main board that I think could be the one, but I'm not really sure. I didn't see anything on the support wiki either. Could someone please point me in the right direction on how to wire it up? (pics would be super helpful if anyone has them as I'm definitely a more visual learner).

Also... at the top, just above the Pi Zero there some little holes for charging indicator LED's... say I was to connect them to a tiny Arduino, instead of an LED would they be sufficient to let me programatically detect the charging status of the battery?

Thanks!

Don´t they need to go to the back board (with USB out / Volume and stuff).
That way you are able to open up the case without problems.

Yep there are cables on the back board. At the bottom is a 3pin cable (included in kit you should have) and also on the one that goes to the power switch there are another 3. You might have connectors on the other end so cut them off.. the ones for L/R are the RED+YELLOW+BLACK cables only. They are labelled on the connector end of the board for their exact function!

You should be able to use those LED holes, you want to make sure that you measure the voltage on the charging one because you will find that it is actually a "switched gnd" so the + pin is always at say 4-5v (batt/usb) and only when it's charging will the - side actually go LOW to GND.. when not charging, it will likely be pulled up to 4-5v or something. I suggest powering your microcontroller from the + and - pads that are near the PGOOD LEDs (this is the batt/usb voltage, and will be the same 4-5v as detailed above).
