atmega328p (Arduno UNO) + esp8266EX (WIFI)¶


micropython code	arduino code	mqtt platform: flespi

It is a customized version of the classic ARDUINO UNO R3 board. Full integration of microcontroller Atmel ATmega328 and IC Wi-Fi ESP8266 with 32 MB (Нашето е с 8мб) flash memory, and USB-TTL converter CH340G (на Linux 5.10.23-1-MANJARO го показва като QinHeng Electronics CH340 serial converter)on one board. All modules can work together or independently.

On the board where the switch of mode of operation with 8 position

To communicate between Arduino and ESP you will need to activate deep switches 1 and 2. To upload a sketch on ESP: 5, 6, 7. (source code in uno_wifi/ino-workspace ) To upload on Arduino: 3, 4. () Don't forget to change board options before uploading when switching.

To see what is transferred to ESP from Arduino: 1, 2, 3, 4. To see what is transferred to Arduino from ESP: 1, 2, 5, 6.
