			In some cases the external power source is out of range and cannot be used, but an external 5V power source is available (for example provided by the ESC). In this case, the external 5V power source must be connected to the "+5V" and "GND" pins of any header that are equipped with them - with the exception of the "5Vaux" pin of the "AUX a" header.<br>
			Limitations:<br>
			*voltage range: 4-6V
			*the external 5V power source must be capable of providing the current needed for: powering the board, and any potential external payload. With a maximum limit of 1A (because of the headers' specifications)
			* the "VBUS" pin of the "USB" header must not be connected to the "+5V" pin of any header
			''Note: with this setup, the voltage of the external power source (VBAT) obviously cannot be measured by the micro-controller (MCU).''

			It is possible to power the Tawaki with only a host computer, through the USB Micro-B port. This setup allows to power the board and all its components, while at the same time flashing it.<br>

			With this setup, the “GND”(-) and “VBAT”(+) pins of the “Servos B” header are used as the main entry ports for the external power source - but only if solder bridge JP1 is jumped (turned ON) with a small blob of solder. This can be interesting when the ESC already delivers the external power source voltage through its command and control signals (as is frequently the case on multi-rotors).<br>
