4.11.1. Power Supply Options

There are two power supply options provided for the Intel® Cyclone® 10 LP FPGA Evaluation Board. The first is USB powered and the second is external AC/DC adapter powered. These two options can be used for different applications. There is an ORING circuit on-board to select suitable power source from USB power or DC jack.


A standard A to Mini-B USB Y-Cable is shipped with the evaluation board. There are three USB ports as listed in the following table.

AC/DC Adapter Power

The DC Jack uses Wurth Elektronik P/N 694106301002 as power input connector.

The required DC mate plug is required to meet the parameters below
  • Inner Diameter (ID): 2.1 mm
  • Outer Diameter (OD): 5.5 mm
  • Voltage: 5 V
  • Center Polarity: Positive (5 V)
Use 5 V adapter for DC Jack J12 only. Components on the board can get damaged by power supplies with greater voltage.
