Voltage mini display 3.3 to 30V - 3 digits
This display falls into the category of affordable measuring equipment. it will be useful even if it is not breathtakingly precise (about 0.4 ~ 0.5 Volts).
This 3-digit display is equipped with two wires and once connected, it measures the voltage at its terminals. You can therefore place it anywhere in a circuit to measure the voltage. So very practical for obtaining information on the operating status.
This display does not need a separate power supply for its own operation, it uses the voltage of the circuit being measured for its own operation.
Simply connect the red wire to the positive pole of the power supply and the black wire to ground. The display is equipped with a microcontroller which reads the voltage and refreshes the display every 500ms.
The meter consumes a current of 3-4mA.
