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.

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

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:

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:
-
Power Test
-
Programming bootloader
-
Passing Arduino IDE programming
test program
-
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.
