ITEADUINO PLUS ARDUINO PLUG

Overview

Iteaduino Plus Arduino Plug is specifically designed for A10/A20 evaluation board. It adapts Raspberry Pi interface on A10/A20 evaluation board to Arduino interface, which facilitates development as Arduino. There is an OLED screen and Grove interface of electronic brick, which is beneficial to prototyping development.
