All electronics ship with US style plugs.You may need a voltage converter or a plug adapter.
Special Features
[IMPORTANT: POWER CONFIGURATION] By default, the onboard jumper (J1) on the back is OPEN, requiring a 5V power supply for VCC and Backlight (BL). To operate the board strictly on 3.3V, you MUST solder the J1 jumper closed. Please verify your voltage before powering on.
[STRICT PINOUT VERIFICATION] Do not rely on universal wiring diagrams; pin directions (Pins 1-16) on this module may be reversed compared to other ST7735 screens. Always verify the silkscreen labels on the back of your specific PCB before connecting to your microcontroller.
[DUAL-ROW EXPANDABILITY] Row 1 comes with pre-installed headers for display functions. Row 2 consists of unpopulated pin holes that break out the Integrated SD Card Slot and additional TFT pins; soldering is required to enable SD storage.
[3.3V LOGIC COMPATIBLE] Even when powered by 5V VCC, this module's logic interface is fully compatible with 3.3V systems like ESP32 and STM32, as well as 5V systems like Arduino Uno.
