Lao Wang 2.5 yuan 3-inch blue backlight LCD12864 adapter board

Overview

### Lao Wang 2.5 yuan 3-inch blue backlight LCD12864 adapter board
I drew my own adapter board and added **backlight control circuit**.
If you choose the LED backlight to be controllable, you need to solder the s8050 and 1k resistor, and short the LED controllable.
If you choose the LED backlight to be always on, short the LED backlight.
#### Note:
**The PCB is processed after being printed to form a structure similar to a stamp hole, which is convenient for welding**
