Basically title.
Because I live in Paris, it would be nice to buy batteries in store. The most promising model I found is a 180mAh 32x17x4mm lipo.
I could also theoretically use one of these li-ion cylindrical batteries, but they are longer than the keyboard’s size (which is 77mm).
Here’s what I already tried:
- removing the inner thumb key, which makes the keyboard 34-key and leaves enough space for the battery mentioned above. Though after a few hours of using home row mods on my current keyboard I don’t think that will be a good solution.
- moving the MCU (Seeed XIAO BLE) to the right, which makes the board 2cm wider (and doesn’t look very good since I have no keys there). This one isn’t very elegant, plus I don’t really want to make the board wider, and I’d like to avoid it even though it is a solution.
Please ignore the mounting holes and TRRS jacks, I am still unsure about whether or not I want to just ditch bluetooth and make this board wired (which works with kmk)
The ergogen config is available on the github repo.
Since you’re going hotswap, you’ve already got about 3mm of space on the back of the PCB. if you make your case just a tad taller, your battery could fit under the PCB.
I’d like to keep the board as flat as possible, mimicking the TOTEM’s case which doesn’t add any height. This means I’ll have 0.2 mm between the main PCB and the bottom plate, and AFAIK there is no battery that would have the correct size for this.
