Pmod CDC1: Capacitive Touch Input Buttons Module The Pmod CDC1 is a capacitive sensor that uses the Analog Devices AD7156. By communicating with the chip via IA2C, users can set the Pmod for an adaptive capacitance threshold that changes with the environment or set static thresholds that only trigger when a certain capacitance is reached. Features Two capacitive input channels Fixed or adaptive threshold capability High sensitivity up to 3 fF Small PCB size for flexible designs 2.3" x 0.8" (5.8 cm 2.0 cm) 24-pin connector with I2C interface Follows Digilent Pmod Interface Specification Shipping Contents One Pmod CDC1 Custom Digilent antistatic Pmod packaging Resources & Downloads Resource Center (off-site) Reference Manual (off-site) Schematic
