Pin 5V_OUT and 3V3_OUT, on simpleRTK2B,   how much current can be source?

It is recommended to not connect this outputs to high power devices. Maximum 100mA.

Thanks for the reply

I see now in the website documentation, that pin 3V3_OUT is described as “..with maximum current output of 750mA …”
So the question is: why this difference between the theoretical 750 mA that the card can deliver and the maximum recommended 100 mA?

Yes that is valid if you don’t use the sockets, but if you use the xbee socket is less. we updated the documentation.
