I am slightly confused by the input voltage. The User Manual shows 6 - 9 volts for external power on the power jack, but 6 - 12 volts for external power on the power header. Visually, I see that these are directly connected. The schematic also refers to 12V.
As my test bed (once it is disconnected from the usb cable) has a +12v source, is this safe? I don’t want to invoke shipping charges for a 9 volt regulator if I don’t have to.
Edit: Did some more research, and the LM1117-5 regulator that is being used by the Panda appears to have an operational rating of 15volts. So, sounds as if it should be OK. If anyone thinks otherwise, please feel free to comment before mine burns up!
