Hi I did some measurements to determine the power consumption of the UDOO x86. You might find the results useful. Setup System: Udoo x86 advanced plus with 32GB SSD OS running from SSD headless with 1 USB device (Logitech Webcam) attached WLAN active OS Ubuntu 16.04 x64 with LXDE Desktop cpufreqtools installed System running Idle: ~260 - 400 mA USB webcam active (accessed via x2go/RDP): ~600-700 mA Firefox Youtube clip: ~600 mA sysbench cpu test with 4 threads: ~500-600mA With keyboard and mDP screen connected: similar values... Sleep states rtcwake (relevant supported states: freeze / mem / disk / off) (note: -s represents the number of seconds to sleep) rtcwake -m freeze -s 10: 200 mA rtcwake -m mem -s 10: 70 mA rtcwake -m disk -s 90: 59 mA rtcwake -m off -s 90: 58 mA Board off = PC off: 58 mA I have not tested the effect of the Arduino 101. The script just had a 'delay(10000)' statement in the loop and nothing else.
