ESP8266 NodeMCU V1 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. The board fits on a half-size breadboard, leaving enough room for Dupont cables on both sides. Compared with the NodeMCU V3, the V1 version is smaller.

Recommended alternative with ESP8266 and USB-C: WeMos D1 mini ESP8266 USB C

Recommended Accessories:

• Breadboard / Hole Grid Plug-In Board Half-Size
• 4-Channel 5V / 3.3V Logic Level Converter
• Logic Level Converter 2-Channel 5V / 3.3V
• 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
