Birdy44 is a handwired split with low-pro switches and Cirque trackpads. Designed by RaphCoder13 aka Standard-Cat-806.

Having completed my Dactyl, I sought to design a portable, low-profile keyboard – Standard-Cat-806.

Inspired by the Claw44, the author added some splay to accommodate the pinkies. MX spacing was used for seamless switching between the Dactyl and this new keyboard.

Specs

• 44x Kailh Choc V1 switches
• 3D printed plate and case
• RP2040-Zero Waveshare controller
• 40 mm Cirque trackpads (scavenged from Steam Controller)
• MBK and 3D printed keycaps
• Magnetic tenting legs
• Transport case

Although the Birdy44 is handwired, the STL files are available in the repo, along with build details and instructions.
