TS-7180 Daughter Card Interface
From embeddedTS Manuals
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). |
