2. Product Overview

2.1. Components

The Akko 5075S kit includes the following main components:

1. Knob: For volume control or other programmable functions.
2. Top Case: The upper housing of the keyboard.
3. Plate: Holds the switches in place.
4. Silicone Plate Foam: Provides sound dampening and cushioning between the plate and PCB.
5. EPE Switch Pad: Further dampening layer for switches.
6. PCB (Printed Circuit Board): The main circuit board where switches are mounted.
7. Silicone: Gasket material for the gasket mount structure.
8. Side LED: Provides additional RGB lighting effects.
9. Bottom Case: The lower housing of the keyboard.

2.2. Key Features

• Gasket-Mounted Structure: This design uses a gasket material (silicone) between the plate and the PCB, creating a 'floating' mount for the switches. This results in a more flexible and cushioned typing experience, reducing harsh bottom-out feel and enhancing acoustics.

• Hot-Swappable Sockets: Equipped with 5-pin hotswap sockets, allowing users to easily install and change mechanical switches without soldering. This supports both 3-pin and 5-pin switches.
• RGB Backlighting: Features full RGB backlighting with a south-facing PCB and additional side LEDs for vibrant lighting effects.
• VIA Software Support: Enables advanced keyboard configuration, including key remapping and RGB customization, across Linux, Mac, and Windows operating systems.
• Akko Double-Shot TPU Plate Mount Stabilizers: These proprietary stabilizers feature POM housing and POM+TPU stems designed to minimize rattle and ping, providing a better out-of-the-box experience. The keyboard also supports screw-in stabilizers.

• Connectivity: The 5075S model connects via USB Type-C wired connection. The 5075B model offers USB Type-C, 2.4g wireless, and Bluetooth 5.0 wireless connectivity.

3. Specifications

4. Setup Guide

The Akko 5075S is a barebone kit, meaning switches and keycaps are not included and must be purchased separately. Follow these steps to assemble and set up your keyboard:

1. Unpack Components: Carefully remove all items from the package: the 5075S keyboard kit, USB-C cable, switch puller, and user manual.
2. Install Switches: Align the pins of your desired mechanical switches with the hotswap sockets on the PCB. Gently press each switch into place until it clicks securely. Ensure the pins are straight to avoid bending. The 5-pin hotswap sockets are compatible with both 3-pin and 5-pin switches.
3. Install Keycaps: Once all switches are installed, place your chosen keycaps onto the switches. Ensure they are firmly seated.
4. Connect the Keyboard: Plug the provided USB-C cable into the keyboard's USB-C port and connect the other end to an available USB port on your computer.
5. Initial Test: Your computer should automatically detect the keyboard. Test all keys and the knob to ensure proper functionality.

5. Operating Instructions

5.1. VIA Software Configuration

The Akko 5075S supports VIA for advanced keyboard configuration. VIA is a powerful, cross-platform (Linux/Mac/Windows) software that allows you to:

• Remap Keys: Customize the function of any key on the keyboard.
• Customize RGB Settings: Adjust lighting effects, colors, and brightness.
• Program Macros: Assign complex sequences of commands to a single key.
• Configure the Knob: Assign specific functions to the rotary knob (e.g., volume control, scroll, zoom).

To use VIA, download the latest software from the official VIA website. Connect your keyboard, and the software should automatically detect it, allowing you to begin customization.

5.2. QMK Firmware

QMK firmware is currently undergoing certification for the 5075S. Users who wish to implement QMK before the official release can download the source code from relevant community repositories.

5.3. RGB Backlighting

The keyboard features per-key RGB backlighting with a south-facing PCB and additional side LEDs. Lighting effects can be customized using the VIA software.

5.4. N-Key Rollover and Winlock

• N-Key Rollover (NKRO): The keyboard supports N-Key Rollover, meaning every key press is registered independently, preventing ghosting or missed inputs even when multiple keys are pressed simultaneously.
• Disable Winlock: The keyboard supports disabling the Windows key to prevent accidental presses during gaming sessions. This function can typically be toggled via a key combination or through VIA software.

6. Maintenance

• Cleaning: Regularly clean your keyboard to prevent dust and debris buildup. Use a soft brush or compressed air to remove particles from between keycaps and switches. For deeper cleaning, carefully remove keycaps and wipe them with a damp cloth.
• Switch Care: When hot-swapping switches, ensure they are inserted and removed gently to avoid damaging the hotswap sockets.
• Cable Management: Keep the USB-C cable organized to prevent strain on the port.
• Avoid Liquids: Do not expose the keyboard to liquids, as this can cause permanent damage.
• Disassembly Warning: Disassembling the keyboard will immediately void the warranty. Please do not attempt to open the keyboard housing unless instructed by official support.

7. Troubleshooting

• Keyboard Not Responding:
  - Ensure the USB-C cable is securely connected to both the keyboard and your computer.
  - Try connecting the keyboard to a different USB port or another computer to rule out port or system issues.
  - If using the 5075B model (wireless), ensure it is charged and properly paired.
• Keys Not Registering:
  - Check if the switches are fully seated in their hotswap sockets. Gently press down on any loose switches.
  - If a specific key is not working, try swapping its switch with a known working switch to determine if the issue is with the switch or the socket.
  - Use VIA software to check if the key has been accidentally remapped or disabled.
• RGB Backlighting Not Working/Incorrect:
  - Ensure the keyboard is properly connected.
  - Use VIA software to adjust RGB settings and ensure lighting is enabled.
  - Check for any firmware updates that might resolve lighting issues.
• VIA Software Not Detecting Keyboard:
  - Ensure the VIA software is the latest version.
  - Try restarting your computer and the VIA software.
  - Ensure the keyboard is connected via USB-C.
• Does it support 3-pin or 5-pin switches?
  - The Akko 5075S features 5-pin hotswap sockets, which are compatible with both 3-pin and 5-pin mechanical switches.
• Does it support magnetic switches?
  - No, this keyboard is designed for standard mechanical switches and does not support magnetic switches.

8. User Tips

• Keycap Compatibility: The south-facing PCB design of the Akko 5075S prevents interference with Cherry profile keycaps, allowing for a wider range of keycap choices without compatibility issues.
• Stabilizer Lubrication: While the included Akko stabilizers are designed to minimize rattle, some users may find further improvement by carefully lubricating them for an even smoother typing experience.
• Experiment with Switches: The hotswap feature encourages experimentation. Try different switch types (linear, tactile, clicky) to find your preferred typing feel and sound.

9. Warranty and Support

For any questions or issues not covered in this manual, please contact the Akko Official Store for assistance. Please note that disassembling the keyboard will immediately void the product warranty.
