Thumbstick click is a high precision input device. It features a dual axis, spring return, pushbutton enabled joystick (similar to the ones used on joypads on popular gaming consoles), and a MCP3204 12-bit A/D converter. The joystick unit receives directional input in the x and y axes by way of two potentiometers connected to a stick. The mechanical pushbutton sends an interrupt signal to the microcontroller. Thumbstick click communicates with the target board through mikroBUS SPI (CS, SCK, MISO and MOSI) lines. The board is designed to use either a 3.3V or a 5V power supply (regulated by the on-board J1 jumper which is soldered to the 3.3V position by default).
