https://gp2040-ce.info/This RP2040-powered gamepad is designed for portrait-mode games. It plugs directly into a smartphone's USB-C port and is compatible with virtually any operating system. No Bluetooth connection or batteries are required as the gamepad communicates directly via USB and acts as a HID controller. The gamepad uses the fantasic GP2040-CE firmware, which also enables a local webserver Web-UI for configuration. All parts of the case and buttons are fully 3D-printable.
