Overview

This article provides information about the power consumption of Colibri VF61 and Colibri VF50 modules used with the Viola Carrier board in different operating conditions.

Colibri VFxx has 0.5 - 1.0 W power consumption depending on the devices connected to it. Below are the power consumption results of several test cases, demonstrating realistic system configurations at various CPU loads for the Colibri VFxx module and Viola carrier board.

Test Notes

• Test results are dependent upon temperature and other operating conditions as well as the Colibri VFxx module and OS & BSP software versions used. These test results are provided as a reference for expected power consumption behavior of Colibri VFxx modules.
• The image used for testing is released version and the power consumption of future image releases is expected to improve.

Test Conditions for Windows Compact Embedded Measurements

• WinCE6, WEC7 and WEC2013 Image version : V1.2
• Power is calculated at input voltage 5.02V.
• All readings are taken at 24-26 degree Celsius room temperature.
• For current and voltage measurement, Fluke 17B digital multimeter is used.
• In idle mode with EDT Display Colibri module by default comes it comes with blue background desktop so it will consume 5-7mA more current then in case of explorer open which is having white background.

Test Conditions for Linux Measurements

• Linux Image version : **V2.4beta1 **
• Power is calculated at input voltage 5.02V.
• All readings are taken at 22-24 degree Celsius room temperature.
• For Current and Voltage measurement, Fluke 17B digital multimeter is used.
