4.9.3.3. Arduino Power

There are several power rails on the Arduino connectors.

  • IOREF: 3.3 V for digital IOs. It must be 3.3 V. 5 V is forbidden as it may damage devices on the board.

  • VCC_3.3V: 3.3 V power generated by Intel® Cyclone® 10 LP FPGA Evaluation Board.

  • VCC_5V_AR1/2: 5 V power from Intel® Cyclone® 10 LP FPGA Evaluation Board.

  • ARDUINO_AREF: Reserved analog reference voltage. Care must be taken that the range can be 0 ~3.3 V. 5 V is forbidden.

When using Arduino connector, USB may not provide sufficient power so we suggest you use external adapter connector (J12) to power up the board.

Arduino UNO R3 did not specify limitation of output current capability. The following table shows the maximum output current for the Intel® Cyclone® 10 LP FPGA Evaluation Board.
