specifications, μQ7-A75-J module needs to be supplied only with an external +5V
®
According to Qseven
power supply.
DC
5 Volts standby voltage needs to be supplied for working in ATX mode.
For Real Time Clock working and CMOS memory data retention, it is also needed a backup battery voltage. All these voltages are supplied directly through card
edge fingers (see connector's pinout).
All remaining voltages needed for board's working are generated internally from VCC power rail.
