2.3 Electrical Specifications

According to Qseven

specifications, Q7-C25 board needs to be supplied only with an external +5V

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 +5V_RUN power rail.

2.3.1

Power Consumption

Q7-C25 module, like all Qseven modules, needs a carrier board for its normal working. All connections with the external world come through this carrier board, which

provide also the required voltage to the board, deriving it from its power supply source.

Anyway, it has been possible to measure power consumption directly on VCC power rail (5V

The power consumption has been measured in a Q7-C25 module with the following configuration on the commercial version:

CPU iMX8M Quad 1.5GHz

RAM DDR4 4GB, eMMC 8 GB

LVDS + HDMI/DP video outputs

Idle

Video 1080p 60fps

GPU working at full load, video output on HDMI

Video 1080p 60fps ,GPU working at full load, CPU 100%

RTC Power consumption on VDD_RTC (when VDD_IN off)

Please consider that power consumption is strongly dependent on the board's configuration, on number of processor cores active and from the interfaces that are

SW enabled.
