Analog Discovery 3 Powering Options

[O.T.]

Hello,

I'm looking for the Powering Options of the "Analog Discovery 3". There are three questions in my mind like this,

1) Can I power the AD3 only with USB Type C with PD feature? If so, Is there any specification for USB Type C power data?

2) What about the barrel-jack powering option? Is 5V 4A power would be enough? Looks like 3.1A is the maximum power the device can draw.

3) Is there any detailed documentation about powering this device up? I found some info in here -->https://digilent.com/reference/test-and-measurement/analog-discovery-3/specifications, But is that all?

 

Looking forward to your feedback..:)

Hi @O.T.,

1) Yes, you can power the Analog Discovery 3 with a USB Type C with Power Delivery; I usually power my device either in this way or through a USB Standard A port that supports the USB 3.x power requirements (in my personal, anecdotal, experience, most standard A ports that are internally connected to a USB 3.x controller are able to supply up to 900 mA without complaint). 

2) A 5 Volt 4 Amp external supply would be able to power the Analog Discovery 3 at its most power intensive state.
I have also used a 5 Volt 2.5 Amp supply to run the Analog Discovery 3 without having the USB connected (you can change the device behavior within the "On Close" option inside the Options dropdown within the WaveForms Device manager), though in that particular instance I was not using the Power Supplies so I was not at risk of overdrawing the external supplies.

3) I am not aware of any additional information outside of the Power Requirements section you referred to in the Specifications (https://digilent.com/reference/test-and-measurement/analog-discovery-3/specifications#power_requirements) or the somewhat inferred material within the LED States section of the Reference Manual (https://digilent.com/reference/test-and-measurement/analog-discovery-3/reference-manual#led_states) that shows whether or not the device has been fully powered on.
I will see about adding in a section in the Reference Manual that adds some additional information about power requirements for the device; thank you for the feedback.

Let me know if you have any questions.

Thanks,
JColvin
