It is another great blue backlight LCD display.

As the pin resources for Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card.

With this I2C interface LCD module, you will be able to realize data display via only 2 wires.

If you already has I2C devices in your project, this LCD module actually cost no more resources at all.

It is fantastic for Arduino based project.

The 10A voltage and current meter itself has a built-in shunt, and the 50A / 100A voltage and current meter needs to be purchased separately (the above options can be checked for purchase).

The power supply voltage of the meter must be 4--30V. If it exceeds 30V, DU stand-alone power supply is required. Please connect according to the figure. The four points of the shunt cannot be changed .

Digital display meter and shunt are used together, 10A can not be used with 50A. 100A shunt.
