I am connecting an Arduino Mega (Crius) to a Intel Embedded processor (Minnowboard) via the following to Peripherals:
- Minnowboard USB -> Arduino (to flash the micro-controller)
- Minnowbaord Highspeed UART -> Arduino UART (to communicate)
Now both the peripherals are supplying +5V Vcc to the Arduino from the Minnowbaord but via different ports. Both the channels shall always remain connected.
Is it safe to power +5V from different ports to the Arduino (because i am technically bypassing all the voltage regulators available on board) ?
Will this cause any problems for the Arduino in regards to difference in voltage levels?
