With the popularity of open-source hardware, Arduino boards are being recognized by more and more users and you can find them in a variety of innovative and creative applications. As it is priced about 20USD, users with insufficient capital budgets will regard its price as too high, which also limits its applications in a large scale of products.

Someone launched a low-cost Arduino-clone board project on Indiegogo before, which meet the needs of many users of low-cost mainboard. As we can see, actually the main control chip influences the cost most. After selection and comparison, we picked out an inexpensive main control chip of strong compatibility with ATmega328 for development, and we programmed Arduino-compatible bootloader and modified IDE configuration for it, so that it can be almost 100% compatible with the present Arduino IDE and various libraries.

We do not simply offer these cheap boards by cloning Arduino board with mass production, but we replace the main control and develop relevant contents to make it compatible with Arduino. Here, we would like to initiate a fund raising for mass production of the board, so that we can further reduce costs through bulk purchasing and processing to provide you with a world's lowest-cost full-sized Arduino derivative board.

Yes, this is the main selling point. If you are the first 50 doners, you can get a unique full-sized Arduino compatible board in the world with 5USD only including shipping cost! If you miss that chance, you still have the unlimited supplies with 8USD which are certainly the world's cheapest! And you can get more benifits by compaigning packages. For details, please refer to the following package information.


Arduino UNO board can only support 5V IO output. If you want to use an external 3.3V module, you will need to ensure security by making a level conversion circuit. On our new board, you can switch the output level 5V or 3.3V only with a flip of level selection toggle switch on Iteaduino Lite, thus you do not need to worry about the level conversion issue any more.

By replacing LDO power supply design with DCDC circuit, it not only offers a wider range of input options, larger output current ( only for 5V), but also reduces the power loss - if you use an external battery as power supply, reduction on power loss will be more evident.


Like Iteaduio UNO, it offers a lot of expansions. However, in order to save costs, these pins will not be welded on it, and you can do it by yourself if needed.


Iteaduino Lite adopts chip LGT8F88A which is highly compatible with ATmega88. Compared to ATmega328 on UNO, FLASH and RAM resources of LGT8F88A are relatively less, yet enough for most simple Arduino applications or getting started.

It has as many digital GPIO and AD interfaces as Arduino UNO, with same SPI, UART and IIC interfaces, thus it can be basically compatible with all the Arduino Shields on the market.

Summary

  • Microcontroller: LGT8F88A
  • Operating Voltage: 5V / 3.3V
  • Input Voltage (recommended): 7-20V
  • Input Voltage (limits): 7-24V
  • Digital I/O Pins14 (of which 6 provide PWM output)
  • Analog Input Pins6
  • DC Current per I/O Pin80 mA
  • DC Current for 3.3V power supply 250 mA
  • Flash Memory 8Kbyte of which 0.7KB used by bootloader
  • SRAM 1 KB
  • EEPROM 504Byte
  • Clock Speed 16 MHz

Due to basically the same internal structure, with use of Arduino IDE expansion package we offered, it is proved that most of Arduino codes can be applied on Iteaduino Lite directly after being compiled.

1) Install driver

To reduce costs, the board adopted CP2102 as USB-to-serial conversion chipinstead of ATmega16U2, and we also used CP2102 on Iteaduino nano. You can download installation instruction for the driver, which contains the downloading address and the tutorial for installing on Windows 7:

DOC_Driver_Installation.pdf

2)Update Arduino IDE

You need to download a native Arduino IDE. The latest version 1.05 can work normally as we have tested, while version 1.5x is unusable. Here you can download the latest IDE software.

After extracting and installing Arduino IDE, you can download the patch package we offered here:

Iteaduino Lite Patch for Arduino IDE.zip

After extracting the zipped file,copyand paste folder Iteaduino Lite to arduino-1.0.5 \ hardware.

Then open Arduino IDE, you can find option Iteaduino Lite below Board, which you can useto upload the code. By the way, do not forget to select serial port first.

3) Bootloader programming

Each board will be programmed with bootloader before leaving the factory, so that you can use it directly after connecting via USB adapter.

If you want to program bootloader by yourself, you can refer to the tutorial on our blog:

Install the bootloeader for Iteaduino Lite

LGT8F88A is a main control chip launched by LogicGreen, which is highly compatible with ATmega88 and with same resources, electrical properties and stability as ATMega88. Moreover, its processing performance is improved through structure adjustment, thus it can work at 32MHz between 1.8V and 5V. In addition, it is equipped with built-in control circuits and registers for touch buttons, which can be easily applied in a variety of small appliances and small projects.

ITEAD STUDIO, the global distributor of this new chip, launched Iteaduino Lite with LogicGreen - an Arduino-compatible derivative board, and offered Ariuino IDE patches and Bootloader, so that you can develop your prototype more quickly. You can use Iteaduino Lite as a evaluation development board for LGT8F88A to develop your project. If you need to order the chip or customized PCB’s for your project, feel free to contact us.

Many users wondered how to program bootloader for Iteaduino Lite or how to download codes to LGT8F88A with use of programmer. Here we would like to recommend SWDICE_mkII programming debugger with open-source hardware:

Opensource SWDICE_mkII debugger and programmer (Using LGT8F88A)

Meanwhile, we are writing codes for Iteaduino Lite that can be uploaded onto the bootloader through Arduino IDE,thus Iteaduino Lite will be able to work as a programmer and can be used to programm codes for those chips without bootloader.

At present, we are working on translation of the documents for the chip, and you can find the translated documents in "Downloads" section. If you have any problems in the process of use, please send E-mails to ITEAD STUDIO, we are glad to help you to get them fixed.

For orders of a single board, we will use simple bubble bags; for orders of more than one board, we will use cartons. Both packaging will be filled with sufficient protectivematerials to ensure the board will not be damaged during transportation.

All SMD components on the board will be welded in advance. For DIP components, we will weld power socket and toggle switch only. To prevent from being damaged, 6pin and 8pin female headers will not be welded as which can be crushed easily, and we will attach them as accessories in the package. All pin locations on the board will remain untouched, so you can buy 2.54mm standard pins on your own.

Pack List:

  • 1x Iteaduino Lite Board without headers
  • 2x 2.54mm 8pin female header
  • 1x 2.54mm 6pin female header
  • 1x 2.54mm 10pin female header


If you know about ITEAD STUDIO, you are sure that we will arrange delivery as schedueled whether we can achieve the funding target or not. The production cycle of the board is about one and a half months, which is expected to be delivered in mid-January, 2014.

If you choose free shipping or airmail,  the parcel will be sent via Hong Kong Post or China Post with non- registered airmail, so we cannot offer you the tracking number to check the shipping progress, and we can only provide you with a number with which you can check in our logistics company website that the parcel is received by them and sent to China Post or Hong Kong Post.

Since we are shipping in mid-January , and the Chinese Spring Festival is by the end of January when the whole country will be given about a 10-day long holiday, and it is often the busiest time with an excess of parcels before the holiday – that is, we do not know whether the parcels received during Christmas have been processed or not yet. Therefore, do not expect to get your parcel in 2 to 3 weeks as usual, you may receive the package at the end of March - although we did deliver the parcel in mid-January, it is normal to take about two months to get it from our experience last year.

So please be noted that: We will send the parckages via non-registered airmails and there will be no tracking numbers offered ! Besides, as it will be sent out in the busiest time period plus a 10-day Spring Festival holiday, you might receive the parcel in about 1 to 2 months! If you are time demanding, you can choose group buying – for example, you can compaign a DHL shipping package which contains 10 boards, and you can distribute them to your group members after receiving it.

As the board is cheap and it is offered to users to make various development, we do not provide any warranties nor accept returns & exchanges, but we do guarantee that each board will be strictly tested before leaving the factory:

  1. Power Test
  2. Programming bootloader
  3. Passing Arduino IDE programming test program
  4. With the test fixture, run the test program to test all GPIO’s and LED indicators to ensure proper functions.

If you cannot accept the above risk terms, we are sorry that we cannot provide you with the products and services.
