3-button wired custom keyboard with USB wired connection and 5V power supply. Features three independent buttons and a rotary encoder. Key value editing software allows customization of each button's key code. Offers three scene modes: media control, software shortcuts, and code copy, with different key assignments per mode. Equipped with a 0.96-inch LCD display that shows the current function of each button based on the active scene. Includes RGB lighting effects and supports standard buttons, multimedia controls, and mouse functions. Hot-swap compatible buttons. Instructions: The three buttons operate independently and must be pressed one at a time—no simultaneous pressing. The rotary encoder supports left turn, right turn, and press actions. A toggle switch controls RGB light on/off. Each button can be assigned a custom key value. Scene switching: Press and hold all three buttons for 3 seconds, then release to enter scene selection mode. Lights will cycle from off to one illuminated LED indicating the current scene: LED 1 = Scene 1, LED 2 = Scene 2. Rotate the encoder to select between Scenes 1, 2, or 3. Assign different key values per scene. After selection, press all three buttons for 3 seconds or unplug and reconnect the USB cable to exit setup mode.
