Power
- V+ - This is the power input. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V. It can be powered between from 3.3V to 5V.
- G - common ground for power and logic.
Display Pins
- CL - This is the TFT SPI clock input pin (SCK).
- DA - This is the TFT SPI MOSI (Microcontroller Out / Serial In) pin. It is used to send data from the microcontroller to display.
- CS - This is the TFT SPI chip select pin.
- DC - This is the TFT SPI data/command selector pin.
- BL - The is the TFT backlight control pin. Tie this pin to ground to turn off the backlight on the display. Otherwise, the backlight will be on by default.
