ESP8266 NodeMCU V3 compatible Development Board

This small microcontroller with WiFi radio module can be programmed with the Arduino IDE. The Micro USB connector is used for programming and power supply. It is suitable for IoT applications, for example a data logger that writes readings to a cloud.

Important: The ESP8266 is a pure 3.3 V controller, all inputs and outputs may only be operated with 3.3 V. A Logic Level Converter is needed for 5 V signals. Because of its width, the board does not fit on a breadboard.

Recommended alternative for a half-size breadboard: ESP8266 NodeMCU V1 compatible Development Board

Recommended Accessories:

• ESP8266 NodeMCU V3 Base Board ProtoShield with Voltage Regulator
• 4-Channel 5V / 3.3V Logic Level Converter
• 0.3m Micro USB 2.0 Cable blue

Features:

• Arduino IDE: enter the URL https://arduino.esp8266.com/stable/package_esp8266com_index.json under Preferences, install «esp8266» in the Boards Manager, select board «NodeMCU 1.0 (ESP-12E Module)»
• To upload, press both buttons RST and FLASH, release RST first, then FLASH
