Voltmeter Module with 7-Segment 0-100V (3 Wires)

Mini voltmeter module with 0.28 inch display, which can display a voltage between 0 and 100VDC.

It is provided with 3 wires, two for power and the third for voltage measurement. Attention , the supply voltage is between 4 and 30 VDC . The supply is made through the Red and Black wires. The third wire (White or Yellow, depending on the batch) will be placed on the Cathode (+), which actually measures the voltage. To work, it is necessary that the circuit has a common GND.

The module has mounting ears. of 33mm.

The decimal point moves automatically.
