The module is fully pin compatible with the Wemos D1 mini, have 16Mb, ceramic antenna with the possibility to switch to an external antenna.

Also the serial chip is CP2104 not CH340.

That you have another pro from another vendor and it totally works certainly rules out your development environment being the issue.

In my experience, so far... I've seen 3 things that cause that endless stutter.
  1. Driver not installed
  2. The flash memory has worn out - I intentionally wore out three ESP-01s to see what happens.
  3. Some wiring on the project was pulling some pin high or some pin low, that isn't tolerated while booting - Do you have any project external circuitry on it?
That's all I've got, but I've never had a CP2104 based USB device. I guess it's time for me to remedy that.

Considering that the price difference between 4MB and 16MB is maybe... a penny or two.

Driver is install and work with another D1 MiniPro buy one years ago.
I upload the firmware on an unplog module so no external circuit.

Arduino IDE compiled and uploaded like a champ... InqPortal recognized the 16MB... then promptly did a Face Plant! Look's like a new update will be coming soon. ;)
