So now that my first Proffie build has been successfully completed, I’m moving on to build #2.
One of the design concessions I made for build #1 means that, to access the usb port for updating the board, I have to remove the control box and outer shroud.
While looking around on a saber supply site, I stumbled on these USB connectors. As the wiring diagram shows a CFX board, I’m wondering if they could be wired to a Proffie in the same way. Most likely I’ll bypass the recharge port and include some kind of a kill switch as I prefer external li-on charging for now and because I read (either here or on Reddit, can’t remember which) that the battery should be disconnected before plugging in to the computer.
Anyone have any thoughts about this or a different solution that would let me make a USB port externally accessible?
Thanks in advance!
Ok, apparently TCSS doesn’t like linux?
If I access their site, and the user-agent of my browser has “Linux” in it, their HTTP server returns no data. If I change it to literally anything else, like “Windows” or “Linax” it works just fine.
The breakout board should work for any board that uses micro-usb though, including Proffieboards.
Of course, if you have a V3 board you don’t need the breakout board, because there are pads on the board for USB already.
I’ve got a 2.2 board for now, but that’s a good reminder for when I move on to saber #3+
Follow up question as I plan out my wiring diagram—if I’m not using a recharge port, my assumption is that I only would only need the data wires to the USB and wouldn’t need to plan for +/ground. If so, could I not just wire up a small usb extension instead?
Tangential, for the 3.7 boards, could I just strip the usb connection from a premade cable and wire direct to the board itself using the appropriate pads?
This is an incorrect assumption. All four wires needs to be hooked up.
Thanks for confirming.
Is there any technical reason, then, that I couldn’t also just use a standard L-shaped usb adapter (or any other micro usb-type extension) to make the port externally accessible?
No reason. Usually the limiting factor is size.
