This low cost sub-miniature LED voltmeter module is ideally suited for high volume applications. It features 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 rows of pins.
