Like others I struggled to find documentation on how to get this up and running. It's running now, and I'm providing some info that may be helpful to others. To Upload to WEMOS 8266 with a FTDI232RL USB To Serial convertor - There probably are other Arduino IDE settings that work, but I've set Arduino Board to Wemos D1 R1, Baud Rate to 115,200. Set COMM Port to whatever is appropriate for your system, then use the standard Compile and Upload buttons (note the Programmer setting is not used). - Physical connections from FTD232RL to Wemos are : TX to D9 (RX), RX to D10 (TX), GND to GND, VCC to 3V3, and FTD232 D3 (GPIO0) to FTD232 GND (required to put WeMOS in flash rather than run mode for boot, remove after download complete. You can leave the other connections and the FTD232 connected so you can monitor serial traffic while running). Note FTD232 CTS and DTR are not needed, also no need for pull up/down resistors, nor a need to push any buttons to reset or start download (but remember D0 to GND during download) Favorite sample doc as referenced in another post. This is a mod to the original that adds weather display but shows example for buttons, display and web server. https://www.esp8266.com/viewtopic.php?f=8&t=17740&p=0&e=0&sid=1bad0a8857210af752c18e769bacaa08

Fan is always on, and comes on even stronger under even minor load. I have another similar spec'd unit (although 30% more money) where the fan only comes on under heavy load and then only part of the time. Also bent the 110/220 selector when trying to make the appropriate setting - had to open the unit to bend it back. Rear fins were bent on arrival. Seems to work fine as a power supply though so if you don't mind the noise and the marginal build quality, go for it.

In spite of having to crazy glue the bottom of the case to stop it from popping out, the overall quality of the case and screwdriver is great.

Ερ: While the board seems to work under the Arduino IDE as a "ESP32 Dev Module", why does the Get Board Info menu item come back with "unknown board"?

Ερ: Anyone know if there's a built-in LED as for other boards, and if so, what GPIO pin is it on.

Gazzaoftok My one I found the inbuilt LED on pin GPIO0

RoyAnderson I also searched for hours. It is on Table 3 of the referenced data sheet but the information isn't nicely laid out in a useful format like some of the competitors products, like the Do-It board. You have to do a little work to reorganize and make sense of it. If I'd known this I'd have bought the Do-It board.
