Pinouts

This color display uses SPI to receive image data. That means you need at least 4 pins - clock, data in, tft cs and d/c. If

you'd like to have SD card usage too, add another 2 pins - data out and card cs. However, there's a couple other pins

you may want to use, lets go thru them all!

3-5V / Vin - this is the power pin, connect to 3-5VDC - it has reverse polarity protection but try to wire it right!

3.3Vout - this is the 3.3V output from the onboard regulator

GND - this is the power and signal ground pin

CLK - this is the SPI clock input pin

MISO - this is the SPI Master In Slave Out pin, its used for the SD card. It isn't used for the TFT display which is

write-only

MOSI - this is the SPI Master Out Slave In pin, it is used to send data from the microcontroller to the SD card

and/or TFT

TFT_CS - this is the TFT SPI chip select pin

RST - this is the TFT reset pin. Connect to ground to reset the TFT! Its best to have this pin controlled by the

library so the display is reset cleanly, but you can also connect it to the Arduino Reset pin, which works for most

cases.

D/C - this is the TFT SPI data or command selector pin

Card CS / CCS - this is the SD card chip select, used if you want to read from the SD card.

Lite - this is the PWM input for the backlight control. It is by default pulled high (backlight on) you can PWM at any

frequency or pull down to turn the backlight off
