OpenLogger Screw Terminal Adapter
The OpenLogger Screw Terminal Adapter is intended to be used with the Digilent OpenLogger to provide external connections to the OpenLogger via screw terminal adapters for more readily accessible inputs. The Screw Terminal Adapter connects directly on top of the OpenLogger to maintain a small form factor.
Features
- Standard Screw Terminal Adapters for easy connectivity
- Designed to fit directly on top of the OpenLogger
Physical Dimensions
The long side of the Screw Terminal Adapter for the Openlogger is 2.838 inches (72.1 mm) and the short side of the PCB is 2.2835 inches (58 mm) in length.
Functional Description
The OpenLogger Screw Terminal Adapter provides screw terminals for each analog input and each digital pin, with an analog ground pin to pair with each analog input. A screw terminal pair for the 5V power supply from the OpenLogger is available in the center of the board as well as additional headers for access to a few of the OpenLogger specific pins.
