So, I was looking around for information about how much current draw from peripherals the raptor is capable of supporting but didn’t see much on the specifications page or with forum searches. On my current project I’m driving a cp7 touch screen and a fairly large array of sensors. Of all the sensors the gas sensors concern me the most because the heater elements can draw +500ma and I’m using two of them driven from an AP5 hub that also is controlling 3 relays and a temperature sensor. I suppose the wifi and cp7 itself may also be candidates for being driven by a dedicated power supply as well.
I haven’t fired up the heater elements in my application yet because of the power concerns. Would it be wise to power the 2 gas sensors or the ap5 hub from their own power source rather than relying on power supplied to the ap5 from the main board? What power limitations have people run into when trying to power large amounts of sensors from their mainboard. Also I’m running the board on a 1 amp 12 volt power supply through the external power module.
