keyboards VS zmk-config-sofle

My own design; https://github.com/tzarc/djinn

You can see an example of this with the Djinn Rev 2a

I have found one with no wireless module (djinn) but i really want a wireless one.

Blood, sweat and ⠀tears were shed, but I think it was worth it. Big thanks to u/tzarc for the great piece of kit and for all folks on the djinn discord channel for putting up with all my noob questions! All the required info is here: https://github.com/tzarc/djinn Now I just have to learn to type better 😂 Here are some progress pics https://imgur.com/a/5h1qPb1

There may be enthusiast mechanical keyboards that use faster ports. My keyboard uses an Elite-C MCU in each half. I've heard some more modern stuff is switching to ARM for the MCUs.

Here's a keyboard that uses an ARM MCU:

Most of the open source designs do not have protection on the TRRS connector. There are many kinds of protection that can be built such as for ESD (static electricity), over voltage, over current (short circuit), noise (interference), etc. All of these require components and board real estate. You can check out the Djinn Djinn keyboard It implements protection on the TRRS port and it is a BEAST. The Pro Micro form factor for MCU boards is pretty small so there is limited space for this kind of circuitry. However, if a keyboard has an onboard controller (no separate microcontroller) it might have some protection, at least on the USB connector.

You can. I learned from this guy: https://github.com/tzarc/djinn. I just don’t remember how (I haven’t used kicad in a while). You might be able to figure it out by looking at the footprints he used here. Even the MCU footprint is a reversible one with all the traces included iirc.

This is wireless with ZMK. I think peripheral side encoder is already solved, though not in the mainline yet. I'm using https://github.com/infused-kim/zmk-config-sofle, but it is not being actively maintained anymore, probably https://github.com/urob/zmk-config would be a more up to date option.

So i am now probably going with a sofle with nice!nanos and for the firmware i have found this but where do i connect the batteries and would a button cell be enoug?

I am using Infused-Kim's Sofle Repo since it fixes the split-side encoder and fixes the OLED power issue.
