A good board with a standard ESP32 chip. The built-in screen is very convenient on an wireless chip. No specs exist, so find the pinout i deduced below.

Had to constantly access the Boot button to program, and ended up breaking the LCD from pulling it out of a 3D printed case.

There are definitely some gotchas with this board. As far as i can tell there is no schematic. I emailed the company (Hiletgo) and no response.Gotcha #1. You must press and hold the BOOT button for a few seconds when Arduino or Pio starts to program. Workaround: solder 1.0uF cap from pin 3 (EN) on the module to pin 1 (GND).Gotcha #2. OLED uses gpio 4 and 5 for I2C. Do not use these for other purposes else your display will not work.Gotcha #3. GPIO12 (Pin MTDI) must be logic low on power up or else micro won't boot up.Gotcha #4. GPIO0 must be logic HIGH on power up or else micro won't boot up.

Five minutes to IoT!This board is very easy to use with the Arduino IDE.1) Add the additional board manager URL by going to File->Preferences2) Add the ESP32 boards by going to Tools->Board->Board Manager and typing "ESP32" in the search bar3) Select "WEMOS LOLIN32" from Tools->Board. Ensure you have the correct COM port.4) Pick a sketch from File->Examples and upload to the board. I used "SimpleTime" which connects to your wifi (enter SSID and password on lines 4 and 5 of the sketch) and gets the current time using NTP. It then echoes this time to the serial monitor. Bottom right shows the client list from my router showing the ESP32 has connected.Great little board for all your internet-enabled projects, the built in display is just awesome for debugging and status.
