Generic ESP32 development board for the development of ESP-WROOM-32 WiFi + Bluetooth microcontrollers. This development board is very economical but it is a little too wide to make assemblies on breadboard.
You can instead opt for the LoLin32 from Wemos as narrow as its little sister the Wemos d1 mini based on ESP8266. It also incorporates a LiPo battery connector ideal for making stand-alone connected objects.
You can also choose this board that incorporates an OLED SSD1306 monochrome screen. The sources of the LoLin32 being Open Source, this manufacturer built its board on the same basis. It is therefore recognized as such in the Arduino IDE.
Finally, for projects that require less space, you can directly buy your ESP32 module to be soldered on a PCB or on a seamless development board (for projects without vibrations or shocks).
