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

Power consumption results

iMX91 Industrial Development Kit Basic

Test condition Input voltage
Vin [V]		 Measured current
I [A]		 Power usage
P [W]
Run mode - U-Boot in command-prompt ready for input 5.195 0.139 0.720
Run mode - Linux booting process (maximum) 5.195 0.161 0.836
Run mode - Linux in command-prompt ready for input 5.195 0.114 0.591
Idle mode - ARM Core off in sleep state 5.197 0.032 0.167
Run mode - Linux running stress test 5.194 0.175 0.909

NOTE:
Values with i.MX 91 Solo 1.4GHz CPU, not with the Basic configuration default i.MX 91 Solo 800MHz CPU.
Will be updated soon.
