How to Use 0.28" DC 0-100V 3-Wire Digital Voltmeter Display Module - Red:

Connections :

Red Wire: Positive of the Power supply (3V DC to 30V DC)

Black Wire: Negative of the Power supply and also used as the negative of the measurement voltage source

Yellow/White/Blue: Positive of the measurement voltage source

If you connect the measuring and power wires of the module to each other, your measurement range will be reduced to the supply voltage range. In 2-wire models, the connection between the power supply wire and the measuring wire is made on the board. (You can also disconnect them)
