Project introduction:
This project is a custom breakout PCB for the ST7789 TFT display, specifically designed to create a spooky Halloween decoration! 🎃

Using an ESP32-C3 Mini microcontroller, this display will show a frightening ghost face animation. This design is perfect for placing in a dark area. When activated, the facial animation looks very realistic and startling, as if a real ghost is watching.

This PCB simplifies the connection between the ST7789 display and the microcontroller, and includes the backlight control circuitry.

Project function:

• Display Animation: The main function is to run a spooky face animation for a Halloween theme on the ST7789 display.
• ESP32-C3 Controller: The project is fully programmed and controlled by an ESP32-C3 Mini.
• Breakout Board: This PCB serves as a clean breakout board for the ST7789 display's pins.
• Backlight Control: The schematic includes a transistor (J3Y) that allows the display's backlight to be controlled (turned on/off) via the BLK pin on the H1 header.

Project Parameters:

• Microcontroller: ESP32-C3 Mini
• Display: ST7789 Display (e.g., 1.54 inch, 240x240 pixels)
• Interface: SPI (Serial Peripheral Interface)
• Operating Voltage: 3.3V
• Main Components (PCB): ST7789 (U1), J3Y Transistor (U2), Resistors, Capacitors.
