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.
The development kits were placed under the high performance conditions - using stress test putting CPU, memories, Ethernet and HDMI under a very heavy load.
Test setup and measuring equipment
- power supply: BK Precision 1688B
- 2x digital multimeter: Fluke 115 True RMS
- measured at: 20°C ambient temperature
