2.8-inch SPI TFT ILI9341 LCD Module - RFJ280J-AYH-DNN

2.8-inch SPI TFT ILI9341 LCD Module with 240x320 IPS Display

Model No. RFJ280J-AYH-DNN

RFJ280J-AYH-DNN is a 2.8-inch IPS active matrix SPI TFT ILI9341 LCD module designed in a vertical (portrait) orientation. It features a resolution of 240×320 pixels with a 3:4 aspect ratio, delivering consistent image performance. The IPS panel provides a wide viewing angle, making this SPI TFT ILI9341 solution suitable for applications requiring stable visual output.

This 2.8-inch SPI TFT ILI9341 module adopts the ILI9341V driver IC and supports MCU/SPI interface configuration. The display offers a typical brightness of 1000 cd/m² with a contrast ratio of 800:1, and operates reliably across a temperature range of -20°C to +70°C. With these characteristics, the SPI TFT ILI9341 design is well-suited for industrial equipment, medical devices, and home appliance interfaces.

IOVCC

Low voltage power supply for interface logic circuits
(2.5 ~ 3.3 V)

Tearing effect output pin to synchronize MPU to frame writing, activated by S/W command. When this pin is not activated, this pin is low.
If not used, open this pin.

Chip select signal.

D/CX(SCL)

(D/CX): This pin is used to select “Data or Command” in the parallel interface.
When DCX = 1, data is selected.
When DCX = 0, command is selected.
(SCL): This pin is used as the serial interface clock in 3-wire
9-bit/4-wire 8-bit serial data interface.
If not used, this pin should be connected to IOVCC or GND.

WR(SPI_D/C)

(WRX) - 8080-Ⅰ/8080-Ⅱ system: Serves as a write signal and writes data at the rising edge.
(D/CX) - 4-line system: Serves as the selector of command or parameter.
Fix to IOVCC level when not in use.

8080-Ⅰ/8080-Ⅱ system (RDX): Serves as a read signal and MCU read data at the rising edge.
Fix to IOVCC level when not in use.
