Hardware Preparation

• FireBeetle ESP32-E (or similar) x 1
• 1.8Inch 128×160 TFT LCD Display with MicroSD Card Slot x1
• Wires

Software Preparation

• Arduino IDE
• DFRobot GDL Library

Wiring Diagram

The following figure shows two ways of connection: SPI and GDI.

Other Preparation Work

1. For using GDI, please make sure your controller has GDI interface.
2. It is recommended to use Arduino version 1.8.10 and above.
3. If the SD card slot is not well connected, the initialization may fail, and it will succeed after unplugging and plugging again.
4. Arduino UNO is not recommended for memory reasons.
5. All the Demos of this product are stored in the file of DFRobot_GDL->ST7735_128x160-.
6. Before burning the Demo, please open the corresponding substantiation function (DFRobot_ST7789_128x160_HW_SPI)
