Research direction

Start by locating the PDF schematic and the corresponding Altium files, then compare how the EN-pin resistor is represented in each. Confirm whether the design uses a pulldown rather than a series resistor; done means the PDF schematic reflects the intended connection and any discrepancy with the Altium source is resolved or documented.

Written by the indexing model from the issue text.

Description

According to Antun_Skuric on the forum the resistor connected to the EN pin was meant to be a pulldown and not a series resistor.

And IMHO that makes very much sense. (I now own 60 bad PCBs...)

I don't know if maybe this was "fixed" in the altium files, but the PDF schematic is lagging, but the PDF shows a series resistor, so at least the PDF should be upgraded.
