A practical walkthrough for setting up the AJAZZ AK820 Pro: learn how to use the knob, customize the TFT screen, and avoid common configuration mistakes.

Quick answer

Start by connecting the AK820 Pro in wired mode, then install the official AJAZZ software. Use the knob for volume and media control by default, and customize the TFT screen through the software to show battery, date, or custom images. Always save your settings to the keyboard before unplugging.

Get the keyboard connected and recognized

Before you change any settings, connect the AJAZZ AK820 Pro using the supplied USB-C cable. This ensures stable data transfer for software detection. If you plan to use it wirelessly later, set that up after your initial configuration.

Open the official AJAZZ software (sometimes called AJAZZ Driver) and wait for it to detect the keyboard. If it does not appear, try a different USB port or cable. Avoid using a USB hub during setup.

Understand the knob's default functions

Out of the box, the knob on the AK820 Pro typically controls volume when rotated and play/pause when pressed. You can change these functions in the software under the 'Knob' or 'Custom' section. Common alternatives include scrolling, zooming, or switching between apps.

If the knob does not respond, check that the keyboard is in the correct mode (wired or 2.4GHz) and that the software is running. Some functions only work when the software is active.

Customize the TFT screen to show what you need

The AK820 Pro's TFT screen can display battery status, date and time, connectivity mode, and custom images or GIFs. In the software, go to the 'Screen' or 'TFT' tab to choose a display mode. You can upload your own images, but keep them small (typically under 1MB) and in supported formats like JPG or GIF.

For battery and connectivity, the screen updates automatically. For custom images, the keyboard stores them in its onboard memory, so they persist even when you switch computers.

Save settings and test before disconnecting

After making changes, always click 'Save' or 'Apply' in the software. The keyboard may flash or briefly disconnect as it writes to memory. Test the knob and screen immediately to confirm they work as expected. If something fails, reconnect and try again.

Step-by-step setup checklist

Connect wired and install software: Plug the keyboard into a USB port using the included cable. Download and install the official AJAZZ software from the EPOMAKER website or the AJAZZ support page. Wait for the software to recognize the device. Checkpoint: The keyboard should appear in the software's device list. If not, try another cable or port.
Set knob functions: In the software, navigate to the knob customization section. Choose rotation and press actions. Common choices: volume up/down, media control, or scrolling. Apply changes. Mistake to avoid: Forgetting to save—changes are lost if you unplug without saving.
Customize TFT screen: Open the screen settings tab. Select a display mode: battery, date/time, connectivity, or custom image. Upload a small image if desired. Preview and save. Checkpoint: The screen should update immediately. If not, reapply settings or restart the software.
Test and finalize: Rotate and press the knob to verify functions. Check that the screen shows your chosen content. If using wireless, switch to 2.4GHz or Bluetooth mode and confirm settings persist. Next step: If you change computers, the onboard memory keeps your settings, but you may need to reinstall software for further changes.
