VF6 System-On-Module (SOM) LC Power Consumption Print

 

This application note provides information on theoretically calculated power consumption of the VF6 SOM LC, as well as some data on "real-life" power consumption of the SOM measured in practical tests.

Please refer to the VF6-SOM-LC-CURRENT_CONSUMPTION.pdf for theoretically calculated power consumption of the SOM in full-power and low-power modes.

The following table provides information on power consumption of the SOM measured in practical tests performed by Emcraft. These numbers are for the SOM itself only (draw @ 3.3V). Power consumed by any components on the baseboard is not accounted for:
