The TS-7180 Daughter Card Interface may be used to connect a variety of off-board peripherals. The interface includes pins for the following:
- I2C
- SPI
- USB OTG
- PoE
- UART (TTL levels)
The table below shows the pinout of the header.
| Pin # | Function |
|---|---|
| 1 | PWR+ |
| 2 | POE_78 |
| 3 | GND |
| 4 | POE_45 |
| 5 | GND |
| 6 | POE_TX |
| 7 | DIO |
| 8 | POE_RX |
| 9 | I2C_DAT |
| 10 | UART_RXD |
| 11 | USB- |
| 12 | UART_TXD |
| 13 | USB+ |
| 14 | I2C_CLK |
| 15 | +5V |
| 16 | +5V |
| 17 | SPI_MISO |
| 18 | SPI_MOSI |
| 19 | 3.3V |
| 20 | SPI_CLK |
| Note: | The default device-tree has an entry for the SPI interface, which will appear in linux as "/dev/spidev2.1".
The UART appears as "/dev/ttymxc7" (when enabled in the FPGA Syscon registers). |
