I am looking to power a spark core v1.0 with an AC/DC converter that has a 5VDC output voltage and 400 mA max output current. I am only using one output pin drawing a max of 10 mA.
I read on (http://docs.spark.io/hardware/) the max current consumption of the core is 300 mA. However in the troubleshooting section (under flashing green) it is noted that a power supply should be able to supply 500 mA and the recommended size of the power supply is 5VDC @ 1A. Can someone clear up this up for me?
