Solder a 0R resistor on this pad or solder directly to connect.
[[File:3.5inch-RPi-LCD-B-Manual-01.jpg|400px]]
Execute the following commands in the Raspberry Pi terminal:
gpio -g pwm 18 1024
gpio -g mode 18 pwm

== '''FAQ''' ==
{{RPI HDMI GPIO LCD FAQ}}
{{FAQ|What are the power requirements?
|When working with 5V input, the current is about 150mA.}}
{{FAQ|If the Raspberry Pi didn't connect to the network during the driver installation, what should I do if the touch is abnormal after that?
|Please try to modify the boot/mark file, change 1 to 0, and then execute the driver installation command after reconnecting to the Internet.}}
