If an external supply is applied to the DAC VDD pin, remove jumper J3 to disconnect the 5-V USB supply from the DAC VDD pin.

J7 can be used to measure the supply current for the DACx3004W. Place jumper J7 to connect the EVM supply to the DACx3004W. Remove jumper J7 and place a current meter between the J7 header pins to measure the current consumed by the ultra-low power DACx3004W.

GPIO2 from the onboard controller is connected to the DAC GPIO pin of the DACx3004W. This input can be controlled through the graphical user interface (GUI) using the controls for GPIO2. If DAC GPIO is configured as an output, remove J6 to disable the GPIOs from the onboard controller.

GPIO3 from the onboard controller is broken out to J1, pin 8 and is controlled through the GUI using the controls for GPIO3.

To enable the GPIO pins, close jumper J6. To disable the GPIO pins, remove jumper J6.
