Overview

This article provides information about the power consumption of the Colibri iMX6ULL module. This information is extracted directly from the Colibri iMX6ULL Datasheet - Section 9.2 Electrical Characteristics.

Colibri iMX6ULL module will have approx 0.4 - 1.2W 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 iMX6ULL module.

Disclaimer

Toradex tests its modules following internal protocols as a way of standardizing the results. The overall power consumption of each module depends on multiple factors, such as:

  • Environmental temperature
  • Particular Silicon Revision of the SoC
  • Versions of the Software Components installed on the module
  • Use cases

The following results were achieved by simulating an ideal scenario. Applications in different conditions may not achieve the exact same results. It is suggested that a customer measures its SoM's power consumption under its own particular use cases before designing hardware based on this data.

Testing Conditions

  • The tests were performed using 3 different modules of each model.
  • The provided data is the average of the results obtained for each module group.
  • All of the SoMs were heated up first (using a stress test) to simulate the conditions of a continuous use scenario.

Note: For a description of each power mode, read the Colibri iMX6ULL Datasheet - Section 6. Power Management.

Note: For the calculation of power consumption, it was considered a 3.3V supply.
