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 hard-
ware consists of a simple open hardware design for the Arduino board with an At-
mel 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 + librar-
ies), 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, mean-
ing "strong friend". The English pronunciation is "Hardwin", a namesake of Ardu-
ino 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.
Arduino has inspired two other major derivates - MAPLE and PINGUINO. Based on 8-bit
AVR technology the computational power of Arduino boards are modest, this is why team
from MIT developed MAPLE project which is based on ARM7 STM32F103RBT6 micro-
controller, the board have same friendly IDE as Arduino and offers the same capabilities as
hardware and software but runs the Arduino code much faster. Maple project can be found

BOARD FEATURES:
We enter in Arduino/MAPLE 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.
1. Original Arduino/MAPLE 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.
2. 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.
3. The original Arduino/MAPLE 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.
4. 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!
5. Our board have UEXT connector which allow many existing modules like
RF, ZIGBEE, GSM, GPS to be connected.
6. Our board have SD-MMC card
7. Our board have CAN driver on board
8. Our desing allow RTC - Real Time Clock.
9. We made our design noise immune.
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 in-
terference 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 Arduino 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 per-
forated boards.
Page 3
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-STM32 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: mini USB cable.
