Typical Pinout and Wiring (Check your module label)

Typical pins you will find on an ST7735 1.44″ SPI module. Confirm the silk-screen or product documentation before wiring.

• VCC – 3.3V supply (do not connect 5V directly to VCC unless module supports it)
• GND – Ground
• SCL / SCK – SPI clock
• SDA / MOSI – SPI data in (MOSI)
• DC – Data/Command select
• RES / RST – Reset
• CS – Chip select (sometimes labeled SS)
• BL / LED – Backlight control (may be tied to VCC through resistor)

Compatibility and Software

This display works well with Arduino, Raspberry Pi, ESP32 and similar boards. Recommended libraries and resources:

• Adafruit ST7735/ST7789 library for Arduino
• TFT_eSPI library for ESP32 and fast rendering
• Community examples and drivers are widely available for Raspberry Pi using SPI
• Check library examples for correct initialization parameters and rotation settings

Applications

• Mini handheld devices and portable electronics
• Smartwatch and wearable displays
• DIY embedded display projects and prototypes
• Robotics status panels and small automation displays
• Arduino, Raspberry Pi, and ESP32 user interfaces
• Educational kits and hobbyist projects

Getting Started Tips

• Power the module with 3.3V where possible; use logic level shifting for 5V hosts.
• Install the Adafruit ST7735 or TFT_eSPI library and load an example to verify wiring.
• Adjust the library initialization and rotation to match your module orientation.
• Use a current-limited 3.3V supply for stable backlight performance on battery projects.
