2.1.1 Power Input [J24] With LED for Status [LD4]

The dedicated power input connector is a USB Type C connector [J24] with Power Delivery 3.0 support. The input can accept wide range of input voltages (5V to 20V). The exact power required for the SK is largely dependent on the application and the connected peripherals. The recommended supplies are listed in Table 2-1. These supplies are 20V Type C supplies capable of supplying up to 100W of power (20VDC at 5A). The minimum supply required is 60W supply (20VDC at 3A). However, a 60W supply may limit available processing with processor as well as limit some of the available peripherals. USB and PCIe peripherals can require significant power and this is a reason higher wattage supply is recommended.

There are many USB Type C power supply manufactures and models available in the market, and it is not possible to test the SK with every combination.

Table 2-1 lists a few recommended supplies the SK has tested.
