[Al B.]

One of two ADP3450s ordered 10/18/2023 fails to run when the temperature is below somewhere around 60 deg F.  Far higher than the specified

"Operating Temperature0 °C to 40 °C (32 °F to 104 °F)"

Error message is:

Pre-heating was required to get the unit operational in  ~ 50 deg F ambient.

The second of the two units works at all temperatures. 

Please replace the following unit:

Hi @Al B.,

Thank you for the detailed information. I agree that the board is suffering from a manufacturing defect and is eligible for replacement.

Presuming that you ordered the device directly from Digilent, please send me a private message with the following information:

• Order number
• Preferred email contact
• (you already provided the purchase date and serial number)

I will then get the information to our Sales team who will contact you to confirm any additional information that I do not have access to, such as shipping address. I will also request the Sales team arranges to have the defective board sent back for analysis.

If you instead purchased the board from a distributor (Mouser, Farnell, Amazon, etc.) you will need to contact them for a replacement. They will then contact Digilent as needed for their own RMA. Feel free to use this Forum thread as evidence of having worked with a Digilent engineer.

Thanks,
JColvin
