DAQCplate (Sparkfun DEV-14148)  I/O options to your Raspberry Pi (Data Acquisition and Controller)

The DAQCplate (Data Acquisition and Controller) from Pi-Plates adds a rich set of input/output options to your Raspberry Pi. It includes seven powerful digital outputs for driving external devices such as relays and high-current LEDs, as well as eight analog-to-digital inputs for measuring temperature, voltage, humidity and more. Additionally, there are eight digital inputs, two analog outputs and seven general-purpose indicator LEDs.

Pi-Plates are a family of stackable and interchangeable add-on circuit boards that allow you to interact with the outside world using your Raspberry Pi. Every Pi-Plate is designed to provide a robust set of features at minimal cost while using the fewest pins possible on the RPi header. Pi-Plates are mechanically and electrically compatible with all revisions of the Raspberry Pi with 40 pin headers (including the Pi 3 Model B and Pi Zero) and are designed to satisfy the needs of hobbyists, experimenters and professionals.
