The TIDBIT PLUS is a high-quality 19-key numpad kit with tons of room for customization | Built around a Pro Micro, rather than a discrete microcontroller. This saves assembly time, and also reduces the build difficulty | The TIDBIT has more programmable keys than a standard 12-key numpad, and allows for multiple layouts | All required parts (diodes, caps, and ICs) are through-hole, meaning they're easy and forgiving to solder | 8x pre-soldered LEDs shine nicely through the acrylic support material. RGB underglow is supported natively in QMK, allowing for easy programming and configuration
