Simple test method:
The J2 jumper of the module is short-circuited by default, which can be cut off to make J2 suspended in the air. The 2,3 legs of the short-circuited CN3 can enter the test mode. When the module is connected to the 5V power supply, the test graphics and characters can be displayed.
