Externally, the promising module turned out to be defective, when you try to use Wi-Fi and power it from USB3.0, it infinitely reboots. Cables are high-quality, ESP-IDF 3.2 and 3.3RC, any other module works under these conditions. If we add an electrolytic capacitor to the output of the 5V module and short-circuit the diode D1, then the module starts to work normally. The voltage drop on D1 is about 0.5V. We must try to replace D1 with a diode with a lower voltage drop.
