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)
| 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 |
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.
