Loading 3D model… large boards can take a moment.
打包 (dǎ bāo or daa2 baau1), which means to take out (food) in Chinese, is a wireless, portable 36-key keyboard with a thumb trackpoint, designed for maximum flexibility and convenience.
Keyboard can be used as a unibody...
... or as a split!
I found that split keyboards can be cumbersome when I’m not working at a desk. Managing two independent halves (as well as a laptop) while moving between coworking spaces, cafés, or even working from the couch quickly becomes unwieldy, and I thought there had to be a better way.
This project explores a keyboard that can seamlessly switch between a unibody form factor (easy to pick up and carry) and a fully split configuration when there's space for a full ergonomic setup. An integrated pointing device is included to reduce the need for external peripherals, making it truly portable.
Albeit unconventional, the trackpoint is positioned under the thumb to:
In practice, using the thumb instead of the index finger feels functionally similar. After a short adjustment period, I personally haven't experienced a meaningful loss in accuracy or precision.
See zmk-config.
Coming soon! - The case will make the magnetic interface more robust, which will allow the keyboard to be lifted from either side without it collapsing in half. Additional magnets will likely be added to make the connection more secure.

Thank you to my sponsors for making this project possible!
The PCBs for this project were manufactured by PCBWay. The boards came out clean with good tolerances and had a fast turnaround, especially considering it came from the other side of the world. Recommended if you're looking to prototype or build your own keyboard!
