GPIOs used by POE+ HAT V1.2

#1

Hi,

I’m successfully using the X4 with its POE hat, but now I need to attach some other periphery to the GPIOs. I have not been able to find any clear documentation which GPIOs are in use by the POE hat. I know there is a 1-wire for the temp sensor. Is there more? which pins are free to use?

Also, as the POE board does not have pin headers installed, what would be the best way to connect to these free GPIOs?

thanks

POE used PIN33 (GPIO13), other GPIOs should be free to use
Maybe you can use the male Dupont cable to connect to the device

That’s odd. On the PCB i can see at least 4 traces on the POE HAT connecting to the pins and on the bottom there are more. I’m not talking about the GND or +5V pins, but GPIOs.
@ryann Is there a schematic available for the HAT (specifically the v1.2 with the 12V connections for the X4) ?

Thanks!

There is SCH for HAT v1.2, not for X4, but no big different
