iMX91 Industrial Power Consumption

This page contains maximum power consumption measurements for the iMX91 Industrial Modules in all 3 standard webshop configurations. All of the COMs 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 and Ethernet/s under challenging conditions.

Test setup and measuring equipment

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