On FME-7, the two ground supplies and three +5V supplies are shorted internally. Boards (like GRM-E301) that were used with the 5A or 5B did not connect pin 27 to +5V.
On FME-7, pin 3 has an overvoltage protection diode only; pin 18 has both over- and under- voltage protection diodes. Functionality is still not known.
