Attention!
The +5 V power supply circuit combines homonymous contacts of the XS1 (PCI-
104), XS2 (PC-104), and XP22 (additional power connector) connectors and is
designed for module's power supply. The +5 V power supply outputs are protected
by a 0.5 A fuse. For connected external modules, the recommended current
consumption value is not more than 0.4 A. It is not recommended to connect power
from interface connectors to more than one external module in order not to overload the power
supply circuits of the CPU module.
GPIO0 port lines are routed to the XP14 connector (IDC2-10, 2-row male connector with a pitch of
2 mm).
Pin assignment of the XP14 connector is shown in Table 4.31.
The module has a Leotronics 2073-3102 connector.
The recommended mating part is Leotronics 2039-3101 (ribbon cable press-on socket).
