VIC3DA Power consumption

[Jad]

Good morning, I want to calculate the power consumption of my teseo vic3DA EVB, unfortunately, the datasheet do not talk about it, I just see in the schematics, it can be powered by 12V, 5V or 3.3V but nothing about the input resistance or the total power consumption.

Hi Jad,

VIC3DA does talk about power consumption in the datasheet.

Please refer to Section 12.3 to get datasheet values.

We also provide power monitor pins but just to make you aware, that captures the entire net and does not capture power to just the module, so there is a slight overshoot but still should give you a good estimation.

The hardware setting is as follows

• CN403 14-pin header provides power monitor pins.
• Measure voltage between CN403-pin-11 (3.3V_GNSS) and CN403-p12 (3.3V_VIC3). The voltage is measured across 0.1 ohm. This measures power consumption during run time.
• To measure VBAT, pin-9 and pin-10. The voltage is measured across 100 ohm here.

Thanks,

George
