Beschreibung
The NodeMCU LoLin V3 is a classic among ESP developer boards.
Equipped with a powerful ESP8266-12F processor and integrated WLAN, this controller offers an easy introduction to IoT development. Due to its widespread use and large community, there are numerous application examples. This board can be programmed both via the Arduino IDE with C and via the Espressif SDK in LUA.
Various firmware versions from the manufacturer are available, which can be easily flashed via the USB-C port. In contrast to the previous model, the CH340 chipset has been used to make the application more user-friendly. Thanks to the generous memory and power reserve of the ESP processor, this board shines in areas where other microcontrollers reach their limits.
