NodeMCU development board based on ESP32

Overview

This is the NodeMCU development board based on ESP32, features WiFi+Bluetooth connectivity, onboard CH340 and keys. What's more, all the I/O pins of ESP32-S module are accessible via the extension headers.

Thanks to the rich open-source resources, it supports development in various ways such as Lua/AT commands/MicroPython/Arduino/IOT source code, etc. helps you to fast prototype IoT applications.

Features

• Onboard ESP32-S module
• Onboard CH340, USB to UART converter
• USB port for power input, firmware programming, or UART debugging
• 2x19pin extension headers, breakout all the I/O pins of the module
• 2x keys, used as reset or user-defined
• Revision log:
• UART converter CH340 is used for new versions, instead of the CP2102. Most Windows systems should recognize it automatically, if not, please download and install the driver.
