Sofle v2.1 Choc Keyboard Battery Case

A sofle choc v2.1 case design to be able to fit a larger volume battery (so that the OLED screen and RGB can stay on without having too short of a battery life.

The case shown fits this battery in the “basement”: https://www.amazon.co.uk/gp/product/B09DPR4V6L

The switches I used were these ones: https://www.amazon.co.uk/gp/product/B086QGZRKG

Please double check with your controller exactly how you should wire everything up, but keep in mind that for these sofle choc PCBs, as they are double sided, there are spare pads for both RAW and GND that aren't occupied by the controller that you can use to make the wiring job cleaner.

The OLED cover spacer was just because for my particular build I socketed both the OLED screen cover and the controller, which made the total height increase, meaning I needed a spacer to raise the acrylic screen cover.

There are two cases shown, one with a cutout for a 3.5mm jack, and one without. If you use the case with a 3.5mm cutout and intend to use the keyboard with a TRS or TRRS cable connecting the halves, then you shouldn't place a battery in both halves. Alternatively if you're using the keyboard with a wireless controller such as a nice nano v2, then don't solder on a 3.5mm jack and use the case without a 3.5mm cutout.
