Wiren Board 5.5: List of GPIOs

The article describes the connection of the built-in peripherals to the processor signals for the Wiren Board 5 (rev. 5.5, 5.6, 5.6.1).

Changes compared to version 5.3

1. Swapped WATCHDOG_IN (37) and MOD1_SCL (35)

2. SDA Mod1 migrated to 11 pin.

3. SPI is now common on all three connectors (SSP2), chip selects are different.

4. CS (MOD1) changed from 11 to 12 pin.

5. CS (MOD2) changed from 12 to 23 pin.

6. CS (MOD3) - 21 pin.

7. MOD3 supply management - 15 pin

8. Порт GSM получил RTS (pin 57) и CTS (pin 59).

9. /dev/ttyAPP4 RS-485 port on RS-485/CAN terminals switched to legs 9 (TX) and 13 (RX), RTS remained at 78.
