LOLIN D32 ESP32 Board 4 MB FLASH
The Lolin D32 is the successor model of the popular LOLIN32. Compared to the Lolin32, some improvements have been made, including lower power consumption in DeepSleep mode. The successor to the ESP8266 also has WiFi and Bluetooth and Bluetooth LE, more IO pins and improved analog inputs. The ESP32 can be programmed under Arduino. However, the board must be integrated first. I recommend the ESP32 only for advanced users, as it is not yet supported by all Arduino libraries. In addition to the WiFi / BLE SoC, the Lolin32 board includes a CH340, which converts USB to serial and allows your computer to communicate with the microcontroller. The LOLIN32 also features a LiPo charger with a connection for 3.7V LiPo's, so you can make your ESP32 project battery-powered and truly wireless. Thanks to the small form factor, the LOLIN32 can be plugged directly onto a breadboard and a jumper cable can be plugged on both sides.
