Power Consumption measurement of iMX91 Industrial Development Kit is successfully finished.
Content of this page will be updated soon.

This page contains maximum power consumption measurements for the iMX91 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 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
