Seeeduino Lite
--------------
![enter image description here][1]
Seeeduino Lite shares many similarities with Arduino Leonardo.
It is a microcontroller board based on Atmega32U4 chip.
The chip has about the same amount of flash, RAM and capability as the ATmega328 found in the Seeeduino.
It has 20 digital I/Os (7 of which can output PWM),a micro USB connection, a power jack, an ICSP header, and a reset button. .
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter to get started.
Seeeduino Lite differs from all Arduino boards in that the voltage select switch affects the I/O output voltage, high level of I/O output is consistent with voltage switch.
And there are I2C Interfaces、UART Interfaces and Grove Interfaces provide convenience for connecting Grove modules.
In addition, Like Arduino Leonardo,The Seeeduino Lite can appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
Features
Each of the 20 digital i/o pins on the Seeeduino Lite can be used a Micro USB to provide power and data to the board and a extern DC power jack can connecte grove module conveniently Can select I/Ooutput Voltage(3.3V or 5V)
IIC and SPI jumper

Introduction
------------
Seeeduino Lite is a microcontroller based on ATmega32U4. Just like Arduino Leonardo, it saves a secondary processor needed for USB to serial communication.
And this allows Seeeduino Lite appear to computer as a USB device, like keyboard and mouse.
Derived from Leonardo, we also merged custom details of Seeeduino series into Seeeduino Lite, like selectable operating voltage, onboard Grove connectors and so on.
It has 20 digital I/Os (7 of which can output PWM),a micro USB connection, a power jack, an ICSP header, and a reset button.
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter to get started.
