The input voltage range (DC-IN) is from 4.75V to 32V, with a typical operating voltage of 13.2V.
The power cable is provided as part of the Fastrack Xtend package.
Caution: Pins 1, 2, 3, 4, 5, 8, 9 and 10 are low voltage interfaces. It is strictly prohibited to connect these pins
to any power supply as there is a risk of damaging the Fastrack Xtend.
5.1.1.1. General Purpose Input/Output
The Fastrack Xtend has two external GPIO ports, GPIO21 and GPIO25; as well as a voltage
reference line, Vref.
Note: For FXT004, GPIO42 and GPIO44 refers to the two external GPIO ports available on the Power
supply connector. Refer to Table 8 Power Supply Connector Pin Description for more information.
