Product Details
● This all-in-one board integrates: an ATmega 328 with WiFi, an R3 ESP8266, and 32MB of RAM.
● All modules can be used individually or together, and each has its own pin header.
● It's a convenient solution for developing new projects with WiFi and USB.
● You can update and build sketches for the ATmega328 and ESP8266 via USB.
● This board includes a CH340G USB-to-serial converter.
● Using this board is very simple.
● The DIP switch board connects the modules.
● For example, a USB port can connect USB to the ATmega328 and ESP8266, or an ATmega328 and ESP8266.
The mode switch allows for four possible settings
● Mode 1 – USB Serial connected to ATMega328 for both programming and serial communication
● Mode 2 – USB Serial connected to ESP8266 for programming
● Mode 3 – USB Serial connected to ESP8266 for serial communication
● Mode 4 – ATMega328 and ESP8266 serial connected together, allowing for serial communication between the two devices. The voltage difference between the Arduino and ESP8266 is taken care of in the board.
A description of the components on the board
● The board includes a 5V and 3.3 V Voltage regulator to allow for the differing voltage requirements for the ESP8266 and ATMega328
● Instead of the large USB connector used on a standard Arduino, this board uses a micro USB connector for serial communication and programming
● The Reset button resets both the ESP 8266 and ATMega328
● The header pin out is standard Arduino; this allows any Arduino compatible shield to be connected to this development board
● The board includes a small WiFi antenna. If greater range is required, provision is made for connecting an external antenna
