The foundation of the JD45 keyboard is a case housing milled from a solid piece of aircraft-grade aluminum. Each case is milled using a CNC process for outstanding precision. Material is 6061 aluminum alloy, which gives the small keyboard a satisfying heft, and a solid, premium typing experience. Finally, the case is anodized in either silver or black color, for that ultimate finished look. Optionally, there is available a version of the case with blocked corners, which emulates the aesthetic of the wildly popular Happy Hacking Keyboard. Available in black or silver colors.

The PCB is the heart of any keyboard. Designed by Wilba, the JD45 PCB features white silkscreen printing on a red solder mask, and comes pre-programmed with a standard layout. It is, however, also fully programmable! With an ATmega32U4 controller on-board, it is compatible with hasu's TMK firmware, metalliqaz's Easy AVR, or other compatible AVR-based firmwares. The PCB is compatible with both MX and ALPS switches, and all components of the assembled keyboard are installed at the factory. DIY PCBs have component electronics pre-soldered, to include diodes and resistors, so the PCB is ready for installation of key switches and optional LEDs.

Included with every assembled keyboard and DIY kit, the switch plate is essential for stable mounting of MX switches. Assembled keyboards will include a color matched anodized aluminum switch plate with standard layout only, which support MX switches. DIY kits will include your choice of switch plate with universal MX mount, in either standard or blocked corner versions.
