- Blue (ALIVE) – Flashing like heartbeat while Kernel is running.
Power 1 x DC jack : outer (negative) diameter 5.5mm, inner (positive) diameter 2.1mm
DC input : 5.5V ~ 13V
- DC 12V/2A power adapter is recommended
Power consumption:
- IDLE : ≃ 1.8W
- CPU Stress : ≃ 3.64W (Performance governor)
- Power-off : ≃ 0.14W

We recommend powering the ODROID-N2/C4 with a good quality 12V/2A power adapter.
However, using a good quality 15V/4A power adapter is also OK if you already have one handy.
There is a bad luck case has reported by our forum, 5V Step-Down Converter(U25) on C4 has damaged when 15V/4A power supply plugged into C4 (☞ https://forum.odroid.com/viewtopic.php?f=205&t=42112).
So we do Not recommend using the 15V/4A Power supply with C4.
Note that 15V/4V is not necessary for the N2, N2+ and C4, 12V/2A is plenty enough. On the other hand 15V/4A is required for the HC4 and the H2 series because these boards may power mechanical hard drives.
