Flexible peripheral modules for all your designs

Pmod™ devices are Digilent’s line of small I/O interface boards that offer an ideal way to extend the capabilities of programmable logic and embedded control boards. They allow sensitive signal conditioning circuits and high-power drive circuits to be placed where they are most effective - near sensors and actuators.

Pmod modules communicate with system boards using 6, 8, or 12-pin connectors that can carry multiple digital control signals, including SPI and other serial protocols. Pmod modules allow for more effective designs by routing analog signals and power supplies only where they are needed, and away from digital controller boards.

Overview Pmod CDC1

The Pmod CDC1 is a capacitative sensor that uses the Analog Devices AD7156. By communicating with the chip via I2C, 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“ × 0.8” (5.8 cm × 2.0 cm)
2×4-pin connector with I2C interface
Follows Digilent Pmod Interface Specification

Scope of Delivery

1 x Pmod CDC1 in a custom antistatic Pmod packaging
