7.2 Assembly Instructions COM Express™ miniBaseboard Type 2
Follow the assembly instruction below to enable Single Supply operation:
To switch CPLD in single supply mode:
» Remove R712 (0R; bottom)
» Mount R711 (1kOhm, bottom)
To enable 5V Standby:
» Mount R46 (0R; bottom)
» Mount R60 (422kOhm; bottom)
To ensure that there is no short with the onboard generated voltages:
» Remove J58 (top), to ensure, that there is no short with the onboard generated voltages possible.
Optional:
» Remove R490 (0Ohm; top) and mount on R491 (top) to enable the power save mode
» Fan is not supported. Remove FB138 (Ferrit Chip Bead, 600 Ohm, 1A, 100MHz; bottom) and place it on
FB137(bottom) to enable Fan output voltage according to baseboard's input voltage or place it on FB136 to
fix Fan output voltage to +5V.
