Needed Increased Range - Delivered!
I wanted to collect some sensor data from an off-grid solar-powered shed and the initial Wemos D1 Mini wasn't able to connect to my Wifi (standard crappy ISP router). Got this one with external antenna and it worked!Easy replacement on the sensor-collecting circuit (same dimensions, drop-in replacement), but keep in mind that to use the external antenna you must rotate a TINY soldered resistor (or just remove it and bridge the other contacts)In my signal strength tests, the external antenna had 10-20 dBs improvement (in my shed I got average -75dB).Be aware of antenna position, and make sure to test signal strength in your application to determine the best orientation (I was surprised that in my case the second-floor router had better connection).

Not the best price.
Board works decently but it's about 4 times the price then if you were buying on alibaba

Board resets continually
I was able to download several different programs to the board, but all of them crash after a few seconds with a watchdog timer reset. I have several other similar boards that work correctly. I will return this defective board.

Did not work reliabily
I was unable to get the board to operate reliability. There was no indication of a software problem; I tried a number of proven example sketches. After many hours of trying to get it to work, I discovered that it would sometimes work if I squeezed the board between my fingers. I suspect that the board had a bad solder joint or two.

Easy to configure, reception is disappointing
I bought this particular ESP8266 option mainly due to it's external antenna for use in a shed with less than ideal wifi reception. I replaced an existing ESP8266 (NodeMCU) module which was using a built-in antenna that worked but the signal was weak. This ends up having the same reception as the old one with the built-in antenna.Other than that, the package is nice and small and easy to configure through the USB connection. I also like having the 5V option right on the board, which helped with my use case.

Previously used
I got one that was previously returned. Some of the pads were already soldered.
