This is a Blue LED Current Meter capable of measuring and displaying current in a circuit up to 10A. It measures 0-9.99A with 2% accuracy. Just apply four wires to your circuit and it will give you a current reading straight away. Easy to use and a good companion to any robot project. Please carefully follow the instructions for wiring. The power supply terminal and measurement terminal of this LED Current Meter use a common-ground connection. So, the measurement must be cascaded after loads. It's better to isolate the power supply.
