iMX7 Power Consumption

Overview

This article provides information about the power consumption of the Colibri iMX7 module used with the Viola Carrier board with different operating conditions.

Colibri iMX7 module will have approx 0.5 - 2.9W power consumption depending on the interfaces used and 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 iMX7 module with Viola Carrier Board.

Test Notes

• Test results are dependent upon temperature, operating conditions, OS version, BSP version as well as which iMX7 module is used. These test results are provided as a reference for expected power consumption behavior of iMX7 modules.
• The image used for testing is beta version and the power consumption of future image releases is expected to improve.

Test Conditions

• Linux Image version : 2.7
• All readings are taken at 24-26 degree Celsius room temperature.
• For current and voltage measurement, YH-112 digital multimeter is used.
• In idle mode with Parallel Display, iMX7 module by default comes with blue background desktop so it will consume 5-7mA more current then in case of explorer open which is having white background.
