NodeMCU ESP32U comes without an antenna, but it works a reasonable distance without an external antenna. An IPEX socket is available to connect an external antenna. Similar to the D and S versions, WiFi+Bluetooth connectivity, onboard CP2102 and keys are included in this version. Similarly all the I/O pins of ESP32 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-U module
• Onboard CP2102, 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
• 2xkeys, used as reset or user-defined
