QT5 Xplained Pro can be connected to several Xplained Pro MCU boards and manually connected to
other hardware. Xplained Pro MCU board(s) that does not have 3.3V as it's primary target voltage will
read all ID devices on connected extensions to check if they support the target voltage before enabling it
to the extension headers. The table below shows the static content written in the ID chip.
