1.28inch Round LCD Display Module, 65K RGB Colors, 240×240 Resolution, SPI Interface,Embedded GC9A01 Driver, Using SPI Bus Features 240×240 resolution, 65K RGB colors, clear and colorful displaying effect SPI interface, minimizes required IO pins, supports controller boards like Raspberry Pi/Jetson Nano/Arduino/STM32 Comes with development resources (examples for Raspberry Pi/Arduino/STM32) Specifications Operating voltage: 3.3V/5V Interface: SPI LCD type: IPS Controller: GC9A01 Resolution: 240(H)RGB x 240(V) Display size: Φ32.4mm Pixel size: 0.135（H）x0.135（V）mm Dimension: 40.4×37.5(mm) Φ37.5(mm) Controlled via SPI Bus VCC: Power (3.3V / 5V input) GND : Ground DIN: SPI data input CLK: SPI clock input CS :Chip selection, low active DC:Data/Command selection (high for data, low for command) RST:Reset, low active BL:Backlight 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) PACKAGE CONTENT 1.28inch LCD Module x1 20cm cable x1
