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).
