SKU:DFR0649 (https://www.dfrobot.com/product-2072.html) (https://www.dfrobot.com/product-2072.html) Introduction This display module features high resolution, low power consumption, wide angle and easy wiring. It employs IPS display with a small size of 1.54 inches, offering 240×240 resolution. The module adopts SPI and GDI interface(work with maincontrollers with GDI port). This LCD display can be powered by 3.3V~5V, and the maximum is power consumption is 24Ma. This product can be used in many display applications: waveform monitor display, electronic gift box, electronic weather decorations, etc. Specification Operating Voltage: 3.3V~5V IPS Angle of View: 80/80/80/80 Color Depth: 16-bit (RGB565) Pixels: 240 × 240 Connection Port: SPI Driver Chip: ST7789 Brightness: 250 (Typ) cd/m2 Brightness: 250 (Typ) cd/m2 Full-screen Power Consumption: about 17mA (3.3V) 17mA (5V) (Typ) Operating Temperature: -30℃~+70℃ Display Area: 27.72×27.72mm Mount Hole Diameter: 2mm Dimension: 44.00x39.00mm Weight: g Board Overview Num Label Description 1 VCC Positive 2 GND Negative 3 SCLK Clock 4 MOSI Data (Master send; Slave receive) 5 MISO Data (Master receive; Slave send) 6 CS Screen Chip Select 7 RES Reset 8 DC Data/Command 9 BL Backlight The backlight has been set to a default value, and can be turned on without connecting the backlight pin. When the backlight pin is connected, input High level(1) to turn the backlight brightness to maximum; Input Low level to turn off backlight. 10 SDCS SD card chip select Dimension Diagram Dimension：44.00x39.00mm/1.73x1.54” Mount Hole Pitch：40mm/35mm Mount Hole Size：2.0mm Tutorial The product is a Breakout module. It adopts SPI communication and has onboard GDI interface, which reduces the complexity of wiring and can easily display the contents read from SD card. NOTE 1. GDI interface could only work well with maincontrollers with GDI. 2. It is recommended to use Arduino 1.8.10 and above. 3. If the SD card is not in good contact, it may fail to initialize, and then please try to replug it.
