Apalis Tegra Power Consumption


This is one of a series of posts about Toradex modules' power consumption measurements. This article provides information about the power consumption of Apalis T30 and Apalis TK1.

The Apalis Tegras's power consumption depends on the devices connected to it. Below are the power consumption results of several test cases, demonstrating realistic system configurations at various CPU loads.


The power consumption is subject to variation, depending on the specific demand of your application, for example, the load, CPU stress, connected peripherals, and temperature. In, our minimum and maximum power consumption estimation is based on the lowest idle power consumption and the highest power consumption values during maximum load on our tests.


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 Conditionsโ€‹

  • 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.
