5IMjGE

The fifth brand offers a 1.75 yuan round screen GC9A01A adapter board.

 
Overview
The schematic design
directly brings out the screen and touch pins, with the CS pin pulled to ground via a 10k resistor.
 
The PCB design
uses an SPI interface driver board, and the screen internal connector is a DF37NB-24DS.
 
Physical demonstration notes:
 
1.
 Solder the internal connector carefully. 2. The previously uploaded PCB design file was carelessly uploaded; it has been corrected. Thank you to user [mytest] for pointing it out.
Other attachments include
diagrams shared by experts.
