The power budget of VCC5V0 is shared by the SYZYGY ports, USB OTG VBUS, RGB
LEDs, and Case Fan. As such, the actual maximum current achievable by each
peripheral varies with the Eclypse Z7's system configuration. Under worst-case
conditions, VCC5V0 is capable of outputting a minimum of 3A of continuous current. In
this scenario, 1A is budgeted for each Zmod
