STD Esp826601+Atmega328P 3.3V
License: Public Domain
Mode: Editors' pick
Adding wifi connectivity to a Artmega 328P with ESP8226-01.
The board is bread board compatible can be powered 5V via any of the FTDI board or the Pin out +5v or can be directly powered from the 3.3V.
3.3V LDO power the esp8266-01 and the Atmega328P. The clock of the Atmega328P is driven by an external 8Mhz oscilator.
Pinout. A6 A7 ADC input are available on the header.
The ESP8266-01 is connected to the Atmegaa328P via serial UART. the ESP8266-01 can be programmed via FTDI. The Atmega can be programmed via FTDI or ISCP port for AVR programmer.
There is a two reset button and on PROG button and and extra button for the ESP8266.
To programm the ESP8266 via FTDI or OTA check my github:
