Power Input/Output Important Note
All power outputs on cable connectors are rated for 1A, however, the system cannot provide 1A simultaneously on all connectors. Contact ModalAI for design assistance.
The difference between VDCIN_5V and VDC_5V_LOCAL is very important. The power module provides VDCIN_5V (raw voltage input) to the platform. On-board is an eFuse that protects the system from accidental wrong-voltage application, droops/brown-outs, or down-stream shorts or overloads. The output of the eFuse is VDC_5V_LOCAL (i.e.: protected output).
