This handy digital module has a built-in 0-100V voltmeter and 0-10A ammeter. You can use it in your hobby circuits to affordably measure voltage and current. Also excellent for use in high school science projects.
1) Connect DC 4-30V to thin black and red wires (minus to black and plus to red) This is the power source required for the meter to operate.
2) Measure current across the two thick black and red wires
3) Measure voltage across the thick black and thin yellow wire
