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.
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:
Th# e 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.
