Electrical Specifications
According to SMARC specifications, the SM-B69 module needs to be supplied only with an ex5V
DC
power supply.
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
DC
power rail.
2.3.1
Power Consumption
SM-B69 module, like all SMARC 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 VDD_IN power rail (5V
DC
) that supplies the board. Power consumption must be intended as average value (30 seconds acquisition).
Independently by the SOC mounted onboard, the following power consumptions are common to all boards:
