I'm new to the community and extremely desperate for help.
I'm get the following error below and this forum is my last ditch attempt at getting the boards working. I purchased what I believe to be an ESP8266 board. I know my Arduino environment and cable are correct because I can get the exact same boards from another vendor to upload without issue. I added a picture below of the board for reference. The only thing I can think of is that board doesn't have a bootloader; similar to how Arduino clones need to be flashed with a bootloader when you first get them. Any help would be greatly appreciated.
The IC on the board is CH340G for reference.
It has new NodeMcu V3 on the back of the module.
