This is version v2.4 modified by 42. Keebs to include a power switch and battery connector for wireless operation and native nice!view support.

Build your very own custom split keyboard from scratch!

• Split 12×3 + 6 (40%-ish) ortho/ergo layout with an OLKB MX spacing (19.00×19.00 mm)
• Supports Kailh Choc V1 switches only
• Uses Kailh Choc hotswap sockets
• Supports in-switch RGB LEDs and RGB underglow
• Optional OLED screens
• Includes a power switch and battery pads on the PCB (v2.3)
  
• Native support for the power-efficient nice!view screens (v2.4)
• Optional mid-plate available for a neater case without gaps
• Fairly easy to build – based on Pro Micro controllers, but uses SMD diodes
• Tinned lead-free finish, black solder mask

⚠️💀 Warning: Never plug/unplug the TRRS cable while the keyboard is powered! It could damage the data pin of the controller. 💀⚠️

Please note, the RGB pin had to be changed to pin 14 (B2 / GPIO23) for native nice!view support. RGB is not supported out of the box when using the nice!nano (minor modification required), and custom Vial firmware is required for RGB support using the Frood (available soon from our firmware page).
