Built a 420g truly wireless CNC split keyboard to fix my coding posture (ZMK)

Hey everyone,

I’m Edan. Like a lot of developers, typing code all day eventually started taking a toll on my wrists and posture. I switched to ergonomic split keyboards a while ago, which helped immensely, but I was always frustrated by the actual hardware available.

Most wireless splits rely on bulky 3D-printed or acrylic cases, and the premium CNC aluminum ones almost always require that annoying TRRS bridge cable cluttering up the desk.

My team and I wanted the best of both worlds, so we spent the last few months developing our own solution: Elytra.

The hardware stack:

  • Firmware: Powered by ZMK.

  • Connectivity: 100% truly wireless. Zero cables to the PC, and no wires between the two halves.

  • Chassis: CNC-machined aluminum. We used a biomimetic cutout pattern on the underside to shave the total weight down to just 420g, making it easy to carry in a laptop bag.

We recently got our site up for early pre-orders: https://elimkeys.com

Since this community is full of developers who care about optimizing their workflows and desk setups, I would genuinely love to hear your feedback on the industrial design. Also, if anyone here has experience tweaking ZMK for optimal BLE stability and battery life, I’d love to chat!
