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.

Switch

  • Level switch

             When it is switched to 5V, Lite works at 5V; when it is switched to 3.3V, Lite works at 3.3V.

 

Button

  • Resetting button

             Press RESET button to reset Lite.

 

Installation

Serial port driver

Iteaduino Lite adopts CP2102 chip instead of ATmega8U2 chip on Arduino UNO, thus we cannot use drive file in drive directory of Arduino IDE to install the driver.

http://www.silabs.com/products/interface/usbtouart/Pages/usb-to-uart-bridge.aspx

You can download CP2102 driver for different platforms including MAC version, Linux version and Windows version. Once downloaded, plug in Iteaduino Lite, search for CP2102 among the unknown devices, then click Upgrade Driver and manually install. Point the driver position to the downloaded driver directory and then install, finally the corresponding serial number can be found on IDE.

More details of installation instructions, you can refer to this file: ftp://imall.iteadstudio.com/Mainboard/IM130615004_ITeaduino_Nano/DOC_Driver_Installation.pdf

Modify Arduino IDE

Download the patch here: ftp://imall.iteadstudio.com/Mainboard/IM131209001_Iteaduino_Lite/Iteaduino_Lite.zip

After extracting it, place folder Iteaduino Lite under directory arduino-1.0.x \ hardware catalog. At present, it does not support Arduino IDE version 1.5.x.

Download program

Select "Iteaduino Lite" when programming.
