Using the 8BitDo SN30 Pro G Classic Edition Bluetooth Gamepad is easy. First, turn on your device's Bluetooth and search for the gamepad. Once paired, you're ready to play. You can choose to pair it as an X - input or D - input device. If you prefer a wired connection, just plug it in using the included USB cable. When using it for robotics projects, connect it to your Bluetooth - enabled robot in the same way. As for maintenance, keep the gamepad clean by wiping it with a soft cloth. Don't expose it to extreme temperatures or moisture. Also, remember to charge it regularly using the USB - C connector to keep the rechargeable battery in good condition.
