Measurements have been performed on the ETRA SOM under test is equipped with:
''TBD: definire la configurazione del SOM in uso'' • i.MX6 DualLite * STM32MP157 Dual Core A7 3D GPU (p.n. MCIMX6U7CVM08ACSTM32MP157AAB3)• 1 GB * 512 MB DDR3L SDRAM• 4 * 8 GB eMMC
1 Gbps Ethernet link has been always active disconnected during the test.
The table below reports the power consumption measurements for the considered use cases.

<code>rtcwake -lt$wakeuptime</code>
