ESP8266 / ESP32S Wireless WiFi + Bluetooth Module NODEMCU Options:ESP8266 Module will illuminate 2 blocks ofNodeMCU is a low cost open source IoT platform. It initially included firmware which runs on the ESP8266 Wi Fi SoC from Espressif Systems, and hardware which was based on the ESP 12 module. Later, support for the ESP32 32 bit MCU was added. The term "NodeMCU" strictly speaking refers to the firmware rather than the associated development kits Features: High performance price ratio Small volume, easily embezzled to other products Strong function with
