The Thumbstick Click Board™ 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. The Thumbstick Click Board™ 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).
MCP3204 12-bit A/D converter
The MCP3204 is a 12-bit Analog-to-Digital Converter (ADC) that is equipped with a successive approximation register (SAR) architecture and an industry-standard SPI serial interface. It allows 12-bit ADC capability to be added to any PICmicro microcontroller. The MCP3204 features 100k samples/second, 4 input channels, low-power consumption (5nA typical standby, 400
