This low cost sub-miniatureLED voltmeter module is ideally suited forhigh volume applications. Itfeatures an exceptionally
large display in a miniature package and includes auto-zero and user-selectable decimal points. The use of low current
display technology means this LED product can be considered for battery powered applications. The OEM 1B-LED is
dimensionally compatible with its LCD counterpart, the OEM 1B. Connection to the module is via two rowsof pins.
