Difference between revisions of "iMX8M Industrial Power Consumption"

Revision as of 12:34, 20 November 2025

This page contains maximum power consumption measurements for the iMX8M Industrial Development Kits in all 3 standard webshop configurations. All of the sets used during the test procedure were running the default Linux distribution and booted up from the eMMC NAND Flash Memory.

Note: While measured, the development kits were placed under a very heavy load - using stress test application putting CPU, memories, Ethernet and HDMI under challenging conditions.

Test setup and measuring equipment

power supply: BK Precision 1688B
2x digital multimeter: Fluke 115 True RMS
digital multimeter: Solartron 7045
measured at: 22°C ambient temperature
