Iteaduino PLUS with A10 core Manual
Overview
ITEAD A10 CORE is a minimum system module based on design of A10 chip. With ARM Cortex A8 core, it
supports maximum frequency up to 1GHz. The high-speed digital circuit section and the overall power
circuit design of SDRAM on the module has been completed, so it can work directly after powering up
with a stable 5V supply.
Iteaduino Plus is a function evaluation baseboard for ITEAD A10 CORE, which breaks out the most of the
interfaces such as HDMI interface, Micro-SD socket, USB socket, SATA interface (data and power),
Ethernet RJ45 interface and audio input / output) socket on the core board module as well as some GPIO
interfaces for users to make secondary development.
Core board and baseboard are designed and sold separately. In the future, we will provide more
baseboards with various functions as well as more powerful core boards to meet the needs from different
users. Users can very easily make secondary development to realize their ideas on such basis, and they
can even design the shields on their own on the basis of the core board- the most complex high-speed
circuit has been modularized, thus design of shields would be relatively easy and simple.
With a variety of powerful library functions offered with ITEAD OS, users can directly manipulate ordinary
GPIO and UART interfaces (which has been achieved in β version), I2C and SPI bus (which will be realized
in V1.0 version), and we will continue to release various library files, such as TFT drive, servo drive, FFT

algorithm, PID algorithm and so on. As a result, users can easily operate different expansion hardware by
calling library functions with ITEAD OS without need to learn the daunting driving principle of linux
kernel. ITEAD OS's goal is to offer users development experience similar to that of Arduino under linux.

c) Select the downloaded ITEAD OS mirror image and Micro-SD card drive. In this case, Micro-SD
card drive is E and OS mirror address is D:/itead.img
d) Click 'Write', select 'Yes' in the pop-up dialogue box,and write ITEAD OS mirror image to
Micro-SD card.
e) System is being written, please wait…
f) After it is successfully written, the system will prompt 'Write Successful'.
g) Withdraw Micro-SD card and then insert it into socket on Iteaduino PLUS, connect to power

supply and monitor, then we can enter the wonderful world of ITEAD OS.
3. Installing ITEAD OS under linux system (let's take Ubuntu as an example)
a) Use shortcut keys Ctrl+Alt+T to open the terminal
b) Insert Micro-SD card into the system and confirm device name of Micro-SD via entering
command fdisk
sudo fdisk -l
As shown in the following figure, in this case, Ubuntu system loads Micro-SD card as /dev/sdc
c) And Micro-SD card file system can be unloaded via command umount
sudo umount /dev/sdc1
sudo umount /dev/sdc2
d) In the folder where img file locates, write mirror image file to SD card via command dd
dd ms=1M if=itead-plus-beat-0814-final.img of=/dev/sdc
e) After the card is successfully written, the system will prompt information such as time spent on
and speed of writing the card.
f) Withdraw Micro-SD card and then insert it into socket on Iteaduino PLUS, connect to power
supply and monitor, then we can enter the wonderful world of ITEAD OS.

 Micro-SD card with system written
If you purchase 8G Micro-SD card from ITEAD, it will have the latest system written; if you already
have a Micro-SD card, you can download ITEAD OS mirror package from the Internet and write it to
the card according to the instructions.
 Mouse and keypad with USB interface
ITEAD OS supports most of the keypads and mouse with standard USB interfaces.
 Connecting to computer through monitor or FOCA
Iteaduino PLUS supports HDMI output, so you can use the monitor that supports HDMI input or
monitor which supports DVI input via HDMI to DVI adapter cable. Alternatively, under circumstances
without graphical interfaces, you can use FOCA to connect to Iteaduino PLUS, and then log in
command interface with software such as putty/secrutCRT/HyperTerminal.
 5V2A charger
When CPU works under large load, voltage loss on USB cable should be considered. If the current is
more than 2A, there will be more than 600mV line loss, and there might be abnormities such as
program running away due to insufficient voltage supply. As power supply from USB port of PC can
only support the system working properly under low load, an external AC ~ DC power supply with
output voltage of a little bit more than 5V is recommended, and the maximum input voltage should
be no more than 6.3V.
Connect all the accessories:
a. Insert the Micro-SD card loaded with operating system into the socket.
b. Connect USB keypad/mouse to USB interfaces on Iteaduino PLUS. You can also connect with a USB
HUB if you have one.
