Electrical Specifications
According to Qseven
®
specifications,
μ
Q7-A75-J module needs to be supplied only with an ex5V
DC
power supply.
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.
