Hi I'm new here in the forum and need help in this
Because it is not possible to connect one sd card to two devices at
the same time
I am looking for a solution that will allow me to switch between the card and two devices
So I drew this -I need to switch the input lines (sd card) between output A to B that representing my two devices
I guess there are many controlers thet can do it - But I do not know much about it
I'm looking for the least complicated option, the cheapest, and most reliable
9 inputs / outputs are actually nine contacts of the SD card, some of which transmit information / identification / Power
