What is it?

This is a low cost Arduino-compatible ESP8266 development board.A 1.3OLED display is on the board. It is very easy for beginners. You can program it like Arduino. There is a project support for ESP8266 chip to the Arduino environment:Arduino core for ESP8266 WiFi chip.

Another famous project is NodeMCU, which you can use LUA to control ESP8266.

This two projects make ESP8266 spread around the world.

Why did you make it?

I have already developed D-duino V2. It seems a lot of people like it. So I extend D-duino with a bigger OLED, makes it look more compact.

What makes it special?

- All ESP8266 pins broken out.

• 12 digital pins write/read/interrupt/pwm/I2C/one-wire supported(except D0)

• 1 analog input

• Integrated 1.3″ OLED

• Micro USB connection

• Compatible with Arduino

• Compatible with NodeMCU(Lua for ESP8266)

Be careful

When you use the example of this library:https://github.com/lspoplove/esp8266-oled-ssd1306 Remember change SDA to D1, SCL to D2. and Change SSD1306 to SH1106.

D1 is always connected to OLED's SDA pin.

D2 is always connected to OLED's SCL pin.

Code example has already been put on github.

Package contains:

• Female pins x1pcs
• Normal pins x1pcs
