INTRODUCTION:
What is Arduino?
Arduino is an open-source electronics prototyping platform, designed to make the
process of using electronics in multidisciplinary projects more accessible. The hardware consists of a simple open hardware design for the Arduino board with an Atmel AVR processor and on-board I/O support. The software consists of a standard
programming language and the boot loader that runs on the board.
Arduino hardware is programmed using a Wiring-based language (syntax + libraries), similar to C++ with some simplifications and modifications, and a Processing-based IDE.
The project began in Ivrea, Italy in 2005 to make a device for controlling student-built interaction design projects less expensively than other prototyping systems available at the time. As of February 2010 more than 120,000 Arduino boards
had been shipped. Founders Massimo Banzi and David Cuartielles named the project after a local bar named Arduino. The name is an Italian masculine first name,
meaning "strong friend". The English pronunciation is "Hardwin", a namesake of
Arduino of Ivrea
More information could be found at the creators web page http://arduino.cc/ and
in the Arduino Wiki http://en.wikipedia.org/wiki/Arduino
To make the story short - Arduino is easy for the beginners with lack of Electronics
knowledge, but also do not restrict the professionals as they can program it in C++
or mix of Arduino/C++ language.
There are thousands of projects which makes the startup easy as there is barely no
field where Arduino enthusiasts to have not been already.

BOARD FEATURES:
We enter in Arduino field 5 years after the design was introduced, and this allowed
us to see and skip all the errors the Arduino inventors did :-)
We had the possibility to read current customer feedback and to implement what
they wanted to see in the original Arduino.
There are few thinks which we made better than the original Arduino design:
1.
We allow the board to work at different frequencies with easily exchange of
the quartz crystal.
2.
Original Arduino uses linear power supply, this limits the input voltage
range. We designed the power supply to accept power from 9 to 30V DC thus making possible to take virtually any power supply adapter on the market, also enable
application which are in industrial power supply 24VDC.
3.
We carefully selected all components to work reliable in INDUSTIRAL
temperature range -25+85C so the board can be used in INDUSTIRAL applications
while the original design is to Commercial 0-70C operating temperature.
4.
The original Arduino design is not good for portable applications as consumes too much power with the linear vltage regulators, we put ULTRA LOW
POWER voltage regulators and the consumption is only few microamps, which enables handheld and battery powered applications.
5.
We add Li-Ion rechargable battery power supply option with BUILD-IN on
board charger, so when you attach battery it is automatically charged and kept in
this state until the other power source (USB or external adapter) is removed and it
AUTOMATICALLY will power the board - no jumpers, no switches!
6.
switch.
Our design can work both on 3.3V and on 5V which is selectable with
7.
Our board have UEXT connector which allow many existing modules like
RF, ZIGBEE, GSM, GPS to be connected.
8.
Our desing allow RTC - Real Time Clock.
9.
We made our design noise immune, there are number of threads on Arduino forum for problems with the RESET when board works with motors, this is because Atmel recommendations were omited in the original design, we fixed this.
10.
We use separate voltage regulator for the Analog part, which allow the
ADC to be read correctly without the digital noise pickup.
11.
Optionally if someone need higher precision and temperature stability in
Analog reading we have provision on the board for Aref preciese source.
12.
The LEDs and the BUTTONs are on the edge of the board so there is easy
access even if the boards have shields on them.
13.
All components are LOWER than the connectors, so the shields do not interference with them.

14.
mini USB connector is used which is common and used in most cell phones,
so you do not have to buy other cables
15.
Original design had flaw and the connectors were not spaced at 0.1" this
make perfo board use impossible, to keep the compatibility we have same spacing
but we add next to this connector on 0.1" which customer can use with perforated
boards.
16.
All signals on the connectors are printed on top and on bottom of the board,
so when you check with probe you know exactly which port you are measuring.
17.
4 mount holes make board attachment easier
ELECTROSTATIC WARNING:
The OLIMEXINO-328 board is shipped in protective anti-static packaging. The
board must not be subject to high electrostatic potentials. General practice for
working with static sensitive devices should be applied when working with this
board.
BOARD USE REQUIREMENTS:
Cables:
You will need mini USB cable for connecting the board to PC. For
programming – the cable you will need depends on the programmer/debugger
you use. If you use AVR-ISP500, AVR-ISP500-TINY or AVR-ISP500-ISO, you will
need USB A-B cable.
Programmer/Debugger AVR-ISP500, AVR-ISP500-TINY,
AVR-ISP500-ISO or other compatible programming/debugging tool.

–
+ 5V from USB
–
3.7 V Li-ion battery
The programmed board power consumption is about 20 mA with all peripherals
enabled
RESET CIRCUIT:
OLIMEXINO-328 reset circuit includes R12 (4.7kΩ), R13 (330Ω), SD5
(1N4148), C7 (4.7nF), C8(100nF), jumper USB_RST, ATmega328P pin29
(PC6/3RESET/PCINT14) and RST button.

JUMPER DESCRIPTION:
USB_RST
LED1_E
D7/D10
This jumper, when closed, enables USB autoreset function. After reset the
bootloader is started and loads the program into the Flash.
Default state is closed.
This jumper, when closed, connects LED1 to D13(SCK) line.
Default state is closed.
When this jumper is closed in position D7 – UEXT pin 10 (UEXT_CS) is connected to
Atmega328P pin 11 (PD7) – signal D7, when this jumper is closed in position D10 - –
UEXT pin 10 (UEXT_CS) is connected to Atmega328P pin 14 (PB2/#SS) – signal
D10(3SS).
Default state is closed in position D7.
INPUT/OUTPUT:
Status Led with name LED1 (green) connected via jumper LED1_E to ATmega328P
pin 17 (SCK/PCINT5/PB5) – signal D13(SCK/LED1).
Status Led with name LED2 (yellow) connected to ATmega328P pin 13
(PCINT1/OC1A/PB1) – signal D9(LED2).
Status Led with name TX (red) indicates that there is transfer in the FTDI.
Status Led with name RX (green) indicates that there is transfer in the FTDI.
Power-on LED (red) with name PWR – this LED shows that the board is power
supplied.
User button with name BUT connected to ATmega328P pin 32
(INT0/PCINT18/PD2) – signal D2(BUT).
User button with name RST connected to ATmega328P pin 29 (PC6/#RESET).
Switch with name SW(3.3V/5V) – selects between 3.3V and 5V power supply of the
board.
