Fan connections (P1100)
Three fans with a supply voltage of 12 Volt can be connected to the module. This takes place with a 2x5-pin
connector. There are also signals for monitoring the fan speed.

GPIO (P504)
The board has a general purpose input/output interface that is fed out via a 2x6-pin connector. By
programming the associated chip (PCA9535BS) accordingly, I/O functions can be created here in a very
flexible manner. Ask your distributor about appropriate software support
