GPIO mapping of APP2.0 shuttle board pins¶
The APP2.0 shuttle board has total 28 pins, of which some have a predefined functionality and some can be used as GPIO by the user.
The shuttle board connector details are given in the table below:
| Pin number on shuttle board | Name / function | Pin number on shuttle board | Name/function |
|---|---|---|---|
| 1 | VDD (3.3V) | 28 | SHTLE_COD #4 |
| 2 | VDDIO (3.3V) | 27 | SHTLE_COD #3 |
| 3 | GND | 26 | SHTLE_COD #2 |
| 4 | SPI MISO | 25 | SHTLE_COD #1 |
| 5 | SPI: MOSI / I2C: SDA | 24 | SHTLE_COD #0 |
| 6 | SPI: SCK / I2C: SCL | 23 | SHTLE_COD_GND |
| 7 | SPI: CS | 22 | IO_4 ( GPIO #4 ) |
| 8 | IO_5 ( GPIO #5 ) | 21 | IO_7 ( GPIO #7 ) |
| 9 | IO_0 ( GPIO #0 ) | 20 | IO_6 ( GPIO #6 ) |
| 10 | SHTLE_COD #5 | 19 | IO_8 ( GPIO #8 ) |
| 11 | SHTLE_COD #6 | 18 | SCL (see note) |
| 12 | SHTLE_COD #7 | 17 | SDA (see note) |
| 13 | SHTLE_COD #8 | 16 | IO_3 ( GPIO #3 ) |
| 14 | IO_1 ( GPIO #1 ) | 15 | IO_2 ( GPIO #2 ) |
Table 1: Overview of shuttle board pins and their functions
Note:
- In coinesAPI the pins are addressed using the same numbers as on the shuttle board. For example, the GPIO #5 has the pin number 8.
- In some cases (depending on the sensor), the I2C lines are shuttle board pin 6 for the clock signal SCL and shuttle board pin 5 for the data line SDA. In such cases pins 17 and 18 may not be connected. Please carefully read the shuttle board documentation.
