Both this and the still to be delivered &quot;Black-Swift&quot; are minimal single board computers using the AR9331. It should be similar to the Black-Swift&#x27;s power specs,<p>&quot;Power consumption: 120 mA typical (400 MHz CPU frequency, Wi-Fi enabled), 60 mA in energy-saving mode (200 MHz, Wi-Fi disabled), 300 mA max&quot;<p>This is at 5v so ~1.5w max. If you wanted to use even moderate power USB2 peripherals instead of the SD card reader you&#x27;d have to inject external 5v power.
