Additionally, an extra capacitor is needed between VDD and VOUT. SCK and SDA pull-up resistors are optional and do not need to be soldered onto the board. The backlight resistor is 100 ohms and can be omitted if backlighting is not required. BL backlight control pin: Default is no connection for on, low level for off. Without the BL control signal pin, the backlight is always on (backlight lights up when powered on). RST reset pin: Solder C5 and R6 as needed. Refer to the comments section on Taobao. The initialization instruction sequence is as follows: Initialization Instruction Sequence Instruction Meaning 0x21 Exit power-off mode, instruction set 01 0x12 Bias=1/9 0xA0 Contrast set 0x20 0x20 Instruction set 00 0x05 PRS=1 (high V0) 0x0C Start displaying. The components were not selected correctly when drawing the circuit diagram. The system-generated BOM is for reference only; please do not place an order directly based on the automatically generated BOM! It uses surface-mount components, a 0603 package, and is 100mm wide, which fits the screen perfectly and is suitable for beginners practicing with a whiteboard. There are still many areas for improvement, so please provide feedback. The ESP8266 used for testing was compiled and tested with the U8G2 library in the Arduino environment (see attached download). The U8G2 library is required; please research other libraries on your own.
