TFT Screen Pins
Digital #13 or ICSP SCLK - This is the hardware SPI clock pin. By default its digital #13. By cutting a jumper and
soldering another on the back, you can move this line from #13 to the ICSP clock pin. This pin is used for the TFT,
microSD and resistive touch screen data clock
Digital #12 or ICSP MISO - This is the hardware SPI master-in-slave-out pin. By default its digital #12. By cutting a
jumper and soldering another on the back, you can move this line from #12 to the ICSP MISO pin. This pin is used
for the TFT, microSD and resistive touch screen data
Digital #11 or ICSP MOSI - This is the hardware SPI master-out-slave-in pin. By default its digital #11. By cutting a
jumper and soldering another on the back, you can move this line from #11 to the ICSP MOSI pin. This pin is used
for the TFT, microSD and resistive touch screen data
Digital #10 - This is the TFT CS (chip select pin). It's used by the Arduino to tell the TFT that it wants to
send/receive data from the TFT only
Digital #9 - This is the TFT DC (data/command select) pin. It's used by the Arduino to tell the TFT whether it wants
to send data or commands
Resistive Touch Controller Pins
Digital #13 or ICSP SCLK - This is the hardware SPI clock pin. By default its digital #13. By cutting a jumper and
soldering another on the back, you can move this line from #13 to the ICSP clock pin. This pin is used for the TFT,
microSD and resistive touch screen data clock
Digital #12 or ICSP MISO - This is the hardware SPI master-in-slave-out pin. By default its digital #12. By cutting a
jumper and soldering another on the back, you can move this line from #12 to the ICSP MISO pin. This pin is used
for the TFT, microSD and resistive touch screen data
Digital #11 or ICSP MOSI - This is the hardware SPI master-out-slave-in pin. By default its digital #11. By cutting a
jumper and soldering another on the back, you can move this line from #11 to the ICSP MOSI pin. This pin is used
for the TFT, microSD and resistive touch screen data
Digital #8 - This is the STMPE610 Resistive Touch CS (chip select pin). It's used by the Arduino to tell the
Resistive controller that it wants to send/receive data from the STMPE610 only
Capacitive Touch Pins
SDA - This is the I2C data pin used by the FT6206 capacitive touch controller chip. It can be shared with other
I2C devices. On UNO's this pin is also known as Analog 4.
SCL - This is the I2C clock pin used by the FT6206 capacitive touch controller chip. It can be shared with other
I2C devices. On UNO's this pin is also known as Analog 5.
MicroSD card Pins
Digital #13 or ICSP SCLK - This is the hardware SPI clock pin. By default its digital #13. By cutting a jumper and
soldering another on the back, you can move this line from #13 to the ICSP clock pin. This pin is used for the TFT,
microSD and resistive touch screen data clock
Digital #12 or ICSP MISO - This is the hardware SPI master-in-slave-out pin. By default its digital #12. By cutting a
jumper and soldering another on the back, you can move this line from #12 to the ICSP MISO pin. This pin is used
for the TFT, microSD and resistive touch screen data
Digital #11 or ICSP MOSI - This is the hardware SPI master-out-slave-in pin. By default its digital #11. By cutting a
jumper and soldering another on the back, you can move this line from #11 to the ICSP MOSI pin. This pin is used
for the TFT, microSD and resistive touch screen data
Digital #4 - This is the uSD CS (chip select pin). It's used by the Arduino to tell the uSD that it wants to
send/receive data from the uSD only
