This page contains 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.

Test setup and measuring equipment

power supply: BK Precision 1688B
2x digital multimeter: Fluke 115 True RMS
measured at 20°C ambient temperature
