Product Description
The Cap Extend Click Board™ is a mikroBUS add-on board with a SEMTECH SX8633 low power, capacitive button touch controller. It has 12 pins for connecting capacitive inputs (either touch-buttons or proximity sensors). Any sort of conductive object can be used as an input. Additional 8 GPIO pins, available on the side-edges of the board, can be used as LED drivers. The SX8633 IC integrates a 10 bit ADC – a resolution high enough to support a wide variety of touch pad sizes and shapes to be used with the click.
The Cap Extend Click Board™ communicates with the target MCU through the mikroBUS™ I2C interface, with additional functionality provided by RST and INT pins. Designed to use a 3.3V power supply only.
