1.28inch Round LCD Display Module 240×240 Resolution 65K RGB LCD HAT for Raspberry Pi 4B/3B+/3B/2B/Zero/Zero W/Zero WH, Jetson Nano,Arduino, STM32,Embedded GC9A01 Driver, SPI Interface

1.1. 28" ROUND LCD DISPLAY MODULE
Embedded GC9A01 Driver, Using SPI Bus
Comes with examples for Raspberry Pi, Arduino, STM32, etc.

2. Controlled Via SPI Bus
Supports Controller Boards Like Raspberry Pi/Jetson Nano/Arduino/STM32

LCD and the controller
The driver used in this LCD is GC9A01, with a resolution of 240RGB×240 dots and 129600 bytes of GRAM inside. This LCD supports 12-bits/16-bits/18-bits
data bus by MCU interface, which are RGB444, RGB565, RGB666.

For most LCD controllers, the communication method of the controller can be configured, they are usually using 8080 parallel interface, 3-line SPI, 4-line
SPI, and other communication methods. This LCD uses a 4-line SPI interface for reducing GPIO and fast speed. LCD

If you are wondering which point is the first pixel of the screen (because the screen is round), you can understand it as a square screen with an inscribed
circle drawn in it, and it only displays the content in this inscribed circle. The pixels in other locations are simply discarded (just like most round
smartwatches on the market)
