What is it?
D-duino means "Display Duino" D-duino-V6 = ESP8266 + TFT screen It is a esp8266 development board.
Why did you make it?
I start D-duino project since 2015. You can check my blog (https://dstike.com/blogs/news/about-those-copycat-products-of-mine) to see the past versions I made. All the past versions revolved around 0.96 OLED and 1.3 OLED. It is time to make D-duino support color TFT screen.
