Uno WiFi R3 Atmega328p NodeMCU ESP8266 8mb Memory USB-TTL CH340G Compatible

Uno WiFi R3 AtMega328p+NodeMCU ESP8266 8mb Memory USB-TTL CH340G Compatible for UNO is full integration on one board: Uno R3 ATmega 328 and WiFi ESP8266 with memory 8Mb (MegaByte). All of the modules can work together or separately. And everyone has their own pinout headers.

The convenient solution for the development of new projects requiring Uno and WiFi. Via USB you can update sketches and firmware for ATmega328 and for ESP8266. For this onboard have the USB-serial converter CH340G.

It is a modernized version of the classic UNO R3 board. Full integration of a microcontroller ATmega328 and a Wi-Fi chip ESP8266 with 8 MB memory on one board. All modules can work together or individually. Each of the microcontrollers has led to connecting peripheral sensors and modules.

A convenient solution for developing new projects that require Wi-Fi. Through USB, you can update sketches and firmware for both ATmega328 and ESP8266. For this on board, there is a UART converter CH340G. The board has a DIP switch, which switches the modes of interaction of microcontrollers ATmegaa328 and esp8266.

Operations of this board are very simple. The board has DIP-switch, to connect the modules. For example, to USB and ATmega328, USB and ESP8266, ATmega328 and ESP8266.
