Using the 8BitDo Lite Bluetooth Gamepad is easy. First, turn on your device (like a Windows machine, Steam, Switch, or Raspberry Pi) and make sure it has Bluetooth enabled. Then, put the gamepad into pairing mode and connect it to your device. You can choose to pair it as an X - input or D - input device. If you prefer a wired connection, just plug the included USB Type - C cable into the gamepad and your device. When it comes to the battery, charge it using the USB Type - C cable when the power is low. It takes about one to two hours to fully charge, and you'll get up to 18 hours of use. Keep the gamepad away from water and extreme temperatures. If the buttons don't respond well, try cleaning the surface gently with a dry cloth.
