Key Applications and Projects

• FPGA Video Generation: Acting as the primary visual output for custom digital logic projects built on the Sipeed Tang Nano 9K development board.

• Wearable Electronics: Building custom smartwatches or health monitors where PCB real estate and power consumption are critical.

• Embedded IoT Dashboards: Displaying real-time temperature, humidity, or network status on ESP32-based smart home sensors.

Unlock New Capabilities (Project Evolution) The Custom Retro Handheld: If you are learning hardware description languages (Verilog/VHDL) on an FPGA, this screen is your gateway to retro gaming! Instead of outputting data to a serial terminal, you can write a custom display controller module in hardware that interfaces with the ST7789 via SPI. Once you master drawing simple shapes and text, you can expand your logic to render entire tilemaps, sprites, and animations, effectively building a tiny, battery-powered 8-bit game console entirely from scratch!

PACKAGE INCLUDED

• 1 x 1.14-inch SPI IPS LCD Display Module 

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What is the diagonal size of this screen? The active display area has a diagonal measurement of 1.14 inches.

2. What is the pixel resolution? The screen has a resolution of 135 horizontal pixels by 240 vertical pixels.

3. What driver IC controls this display? The display is driven by the industry-standard ST7789 controller chip.

4. Is this an IPS or TN panel? This is an IPS (In-Plane Switching) panel, which provides significantly better color accuracy and wider viewing angles than older TN panels.

5. How does this screen connect to my circuit board? It connects via an integrated Flexible Printed Circuit (FPC) ribbon cable that slides into an 8-pin ZIF socket.

6. What is the pitch of the golden contacts on the ribbon? The contacts have a standard spacing (pitch) of 0.5mm.

7. Is this the exact screen used on the Sipeed Tang Nano 9K? Yes, this NFP114H-03AF module is the exact direct-fit screen that is optionally bundled with the Tang Nano 9K FPGA board.

8. What is the operating voltage (VDD)? The display logic operates at 3.3V DC. Applying 5V directly to the data pins may damage the ST7789 controller.

9. What does the "LEDA" pin (Pin 1) do? LEDA stands for LED Anode. This is the positive power input that illuminates the backlight behind the LCD panel.

10. What does the "RS" pin (Pin 4) stand for? RS stands for Register Select (sometimes labeled as DC for Data/Command). It tells the ST7789 whether the incoming SPI data is a configuration command or pixel color data.

11. Does this screen have touch capabilities? No, this is a display-only module and does not include a capacitive or resistive touch digitizer.

12. What are the physical dimensions of the glass body? The rigid glass portion of the display measures 17mm wide, 31mm long, and 1.6mm thick.

13. What is the total length of the component? From the top of the glass to the very end of the extended flexible ribbon, the total length is 54mm.

14. What is the width of the flexible ribbon cable? The narrow neck of the FPC ribbon cable is 4.5mm wide.

15. Can I use this screen with an Arduino or ESP32? Yes. You will need a custom PCB or a breakout board that converts the 0.5mm ZIF socket into standard 2.54mm pins, but the ST7789 SPI protocol is fully supported by Arduino libraries.

16. Do I need to solder the ribbon cable? No, the ribbon is designed to be pressure-fitted into a matching FPC/ZIF connector on your host motherboard.

17. Why is there a green tab on the front of the glass? The green tab is attached to a thin, protective plastic film covering the screen. You should peel this film off using the tab before final installation.

18. What do the SDA and SCL pins do? These are the SPI data lines. SCL is the Serial Clock line, and SDA is the Serial Data (MOSI) line used to push pixel data to the screen.

19. What is the "CS" pin for? CS stands for Chip Select. Pulling this pin LOW tells the screen to listen to the incoming SPI data, allowing you to share the SPI bus with other devices.

20. Does this display support full 16-bit color? Yes, the ST7789 driver supports standard RGB565 (16-bit) color formats, allowing for vibrant, full-color images.
