GPIO mapping of APP3.0 shuttle board pins

The APP3.0 shuttle board has a total of 16 pins, 7 on the left and 9 on the right.(with shuttle board pins facing downwards).

Note:

  • In coinesAPI the pins are addressed as on the APP3.0 shuttle board. For example, the GPIO #5 is addressed as COINES_MINI_SHUTTLE_PIN_2_6.
  • Supported VDD voltages on APP3.0 board are 0, 1.8V and 2.8V.

  • Supported VDDIO voltage on APP3.0 board is 1.8V.

    Pin number on shuttle board Name / function Pin number on shuttle board Name / function
    1_1 VDD (1.8/2.8V) 2_1 SPI_CS
    1_2 VDDIO (1.8) 2_2 SPI: SCK / I2C: SCL
    1_3 GND 2_3 SPI: MISO / I2C: SDO
    1_4 GPIO0 2_4 SPI: MOSI / I2C: SDA
    1_5 GPIO1 2_5 GPIO4*
    1_6 GPIO2 2_6 GPIO5*
    1_7 GPIO3 2_7 IOXP_INT*
    2_8 PlugDet*
    2_9 EEPROM_RW

    *SPI pins for secondary interface - CS:GPIO4, SCK:GPIO5, MISO:IOXP_INT, MOSI:PlugDet
