Wiring Instructions
The first connection method: external power supply, you only need to connect the red and black power lines, and the yellow line does not need to be connected (the purpose is to supply power to the display); the working voltage cannot exceed 5V. (Note: If it is connected to an external power supply, the product cannot be installed with a battery, otherwise an abnormality will occur).
The second connection method: needs to be connected, and it also needs to be wired, but there is an extra resistor, which needs to be connected as shown in the figure below. In this case, battery power supply must be added, because connecting to requires separate power sup
