Pierce v2 by durken1

pierce 2.0 is a split modular wireless / semi-wireless 36 key column staggered keyboard. The design is inspired by Corne with more pinky stagger as well as only using 1u keycaps. It is possible to build a wireless version or a semi wireless version. If building the wireless version an additional reciever dongle is required. In the semi wireless version the wired half is also acting as a reciever for the wireless half. Both versions have full QMK support.

The semi wireless version has a built in reset circuit for connecting a PS/2 pointing device.

There are 3 different PCBs: wireless (reversible), wired (right) and reciever.

Porcupine by anarion80

Porcupine is an autogenerated, ergonomic, split, 36-42 key, wired/wireless, columnar-staggered keyboard. It is designed to fit my needs and my hand, but it can be easily updated thanks to declarative design. It uses a ProMicro-compatible MCU board and supports both QMK and ZMK firmwares.

Features
* Autogenerated - PCB layout is declared using YAML config files and generated into PCB files using Ergogen tool (migrated to V4). Use my fork of it for added footprints.
* 3 variants (5x3+3; 5x3+4; 6x3+4)
* Wired or wireless
* Low-profile (using Kailh Choc switches)
* Reversible PCB (save cost in production)
* Pro-micro/Elite C/Proton C/nice!nano support
* Hot-Swap support
* SplitKB Tenting puck support.
* Uses KiKit to render PCB previews (see below)
* Uses KiBot to run DRC, create Gerber and Drill files for production (and Interactive BOM and 3d renders just for fun)

Oddball by atulloh

The Oddball is a split mechanical keyboard with an integrated trackball. While drawing inspiration from things like the Jian and the Dactyl Manuform, it is instead designed with a switch plate and PCB to give it durability, replicability, and a more utilitarian look. It has a relatively minimal key layout, typically with 39 keys in total. The PCB is reversible so it can be built with 0, 1 or theoretically 2 trackballs. Due to the height and angle of the optical sensor, and as an ergonomic bonus, it requires a tented case.

Features
* Split design
* 39 keys
* Trackball
* Dynamic CPI (trackball cursor speed)
* 5° typing angle
* 8.5° tenting angle
* Angled thumb clusters
* QMK firmware

The Owl by sapristi

The Owl is a 36-key (diodeless!), MX-spaced, wireless keyboard.

It was forked from the rae-dux (itself inspired by the Architeuthis Dux).

The main difference with the rae-dux is that MX-spacing is used for the keys. This keyboard is also designed with top and bottom plates, so as to protect the MCU and the battery. The mounting holes will fit m3 screws / standoffs.

Note: the top-plate doesn't need the mounting holes, so you could remove them from the kicad files.
