3. Setup
3.1. Case Assembly
The KBDcraft 02Lilith features a unique brick-built case design. Follow these steps to assemble the keyboard case:

- Carefully connect the brick pieces according to the included assembly diagram to form the base and top frame of the keyboard case. The case is designed with a 5.5-degree ergonomic tilt.
- Ensure all connections are secure to provide a stable foundation for the internal components.


3.2. Component Installation
Once the case is assembled, install the internal components:
- Place the PCB and plate assembly into the assembled case. The gasket mount design will provide a cushioned typing experience.
- Install the switches into the hot-swappable sockets on the PCB. Ensure each switch is aligned correctly before pressing it firmly into place.
- Attach the keycaps to the switches. Use the provided keycap puller if needed for precise placement or removal.

3.3. Connecting to Your Computer
Connect the keyboard to your computer using the provided USB-C cable:
- Insert the USB-C end of the cable into the port on the keyboard.
- Insert the USB-A end of the cable into an available USB port on your computer.
- The keyboard is plug-and-play and should be recognized automatically by your operating system (Windows/macOS).
4. Operating Instructions
4.1. Basic Keyboard Functions
The KBDcraft 02Lilith Q 75% keyboard operates as a standard QWERTY layout keyboard. All standard keys function as labeled. The 75% layout includes essential keys while maintaining a compact form factor.

4.2. Hot-Swappable Switches
The keyboard features hot-swappable sockets, allowing you to change mechanical switches without soldering. This supports both 3-pin and 5-pin switches.
- To remove a switch, use a switch puller (not included, but recommended for switch changes) to gently grip the top and bottom clips of the switch and pull upwards.
- To install a new switch, align the pins of the new switch with the holes on the PCB. Ensure the switch is oriented correctly.
- Press the switch firmly until it clicks into place. Do not force the switch if it does not go in easily; check for bent pins.

4.3. RGB Lighting Control
The keyboard supports RGB backlighting with over 40 different effects. Use the following key combinations to control the lighting:
- FN + W/E: Change RGB Brightness.
- FN + Left/Right Arrow: Change RGB Modes (cycle through effects).
- FN + Q: Turn On/Off RGB.

4.4. QMK/VIAL Customization
The KBDcraft 02Lilith keyboard is compatible with open-source QMK firmware and programmable via VIAL for advanced customization. VIAL allows for real-time key remapping, macro creation, and RGB lighting customization without needing to recompile firmware.
- Download the VIAL software from the official VIAL website (get.vial.today).
- Connect your keyboard to your computer.
- Launch the VIAL application. The software should automatically detect your keyboard.
- Use the VIAL interface to remap keys, create macros, and customize RGB effects. Changes are applied in real-time.

4.5. Left-side Macro Pad
The keyboard includes an innovative 10% PCB on the left side, featuring 8 FN keys and 1 additional function key for extended control and macro capabilities. These keys can be programmed using VIAL software to perform specific actions or complex macros.

5. Maintenance
5.1. Cleaning
Regular cleaning helps maintain the keyboard's appearance and functionality:
- Disconnect the keyboard from your computer before cleaning.
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down the keycaps and case.
- For dust and debris between keycaps, use compressed air or a small brush.
- Avoid spraying liquids directly onto the keyboard.
5.2. Keycap and Switch Replacement
Refer to section 4.2 for instructions on replacing switches. To replace keycaps, gently pull the keycap upwards using the provided keycap puller. Align the new keycap with the switch stem and press down firmly until it is seated.
6. Troubleshooting
6.1. Keyboard Not Responding
- Ensure the USB cable is securely connected to both the keyboard and the computer.
- Try connecting the keyboard to a different USB port on your computer.
- Test the keyboard on another computer to determine if the issue is with the keyboard or the computer's port/drivers.
- If using a USB hub, try connecting directly to the computer.
6.2. RGB Lighting Not Working
- Ensure RGB lighting is not turned off (press FN + Q).
- Check brightness levels (press FN + W/E).
- If using VIAL, ensure the lighting settings are correctly configured and applied.
- Restart your computer.
6.3. Keys Not Registering
- Remove the keycap and switch for the non-functioning key.
- Inspect the switch pins for any bends or damage. Straighten bent pins carefully or replace the switch if damaged.
- Reinsert the switch firmly into the hot-swappable socket.
- If the issue persists, try swapping the switch with a known working switch from another key to isolate the problem.
