Datasheet

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.
