<![CDATA[EN pin.]]>What is the EN pin supposed to be?

On my ESP32C3 I measure VCC (3.3V)

But on my ESP32S3 I measure 4.6V (with a 3.30V VCC, and 5.01V USB power.)

The latter I find very strange?

The EN is connected to VIN, not VCC, via a diode, which drops it a little below the 5V from USB.

This is different from the Stamp-C3, but I guess that's fine.
