Overview

Iteaduino Lite is a new Arduino mainboard based on LGT8F88A compatible with Arduino interfaces. With 14 digital input and output pins (of which 6 pins can be used for PWM output), 6 analog inputs and SWD debug interface, the operating frequency can reach up to 32MHz. Compared to other Arduino mainboards, it runs faster with more powerful functions. It is compatible with most of Arduino libraries, and the development is as simple as Arduino.
