Proffie lite board replacement and USB-C charging

Hey there. First time user of Proffie board.
I’m one of the suckers that bought an Ultrasabers neopixel proffie lite… I know, I should have done my research first. :frowning:

I’m having trouble with it turning itself on/on rapidly or simply stops responding and locks up.
It seems like a loose wire as sometimes it works fine. and if I pull the chassis out it fixes it sometimes. So, if I have to take it apart to find the problem, I might as well replace the controller while I’m at it. So, I purchased a Proffie V3.9.

  1. Will I have to change any resistors to the led’s or neopixel data pins? It has a single RGB momentary power button and the pixel blade.

  2. I’d like to add a USB-C charge port. From what I’ve read. I should be able to add a panel mount USB-C Charging port to the Vbus and Gnd pins on the board. Is this correct?

  3. Do I have to have a kill switch? I’d rather not have to cut another hole in the hilt.

Lastly, are there any tips on how to disassemble the saber? It’s a Guardian model.

I appreciate any help!

No idea, since I don’t know what’s in there today.

That should work, but why not find something that also breaks out D+ and D- so you can program the board from the same port as well?

Having some way to cut the power completely is recommended.
Is the battery removable? If so, then you don’t need a kill switch.

Thanks. Good point about the existing resistors. I’ll have to look into that.
As for the data usb-C. I wasn’t able to find anything that had a “rim” on it that would hide any poor cutting edges. I can look a little harder.
And yes, the battery is removable when it’s on display I plan to take it out.

If I end up connecting the D- and D+ to a usb-C connector, is it D- to D- and D+ to D+ on the board,
or is it reversed like Serial connections. IE, RX - TX and TX - RX?

Thanks again.

D+ to D+ and D- to D-.
