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 + li-
braries), similar to C++ with some simplifications and modifications, and a Process-
ing-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 af-
ter 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 Ar-
duino of Ivrea.

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 derivatives – 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 microcontroller, 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 at
http://leaflabs.com
In parallel with Arduino another project was started called
PINGUINO.
This
project choose the first implementation to be with PIC microcontrollers, the reason
was that AVRs were hard to find in some parts of the world like South America so
you will see lot of
PINGUINO
developers are from there.
PINGUINO
project
founders decided to go with Python instead Java for processing language. For the
moment
PINGUINO
is much more flexible than Arduino as not limited to 8bit, cur-
rently the IDE which have GCC in background can support 8-bit PIC microcon-
trollers, 32bit PIC32 (MIPS) microcontrollers and ARM7/CORTEXM3 microcon-
trollers which makes
PINGUINO
very flexible as once you make your project you
can migrate easily through different hardware platforms and not being connected to
single microcontroller manufacturer. The PINGUINO project can be found at

BOARD FEATURES:
We entered the Arduino/MAPLE field 5 years after the introductions of the design,
and this allowed us to see and skip most of 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.
The original Arduino/Maple uses linear power supply, this limits the in-
put voltage range. We designed the power supply to accept power in the 9 to 30V
DC range thus making it possible to take virtually any power supply adapter on the
market; this also enables application which are in industrial power supply 24VDC.
2.
We carefully selected all components to work reliable in
the INDUSTIRAL
temperature range -25+85C
so the board can be used in INDUSTIRAL applications
while the original design is up to the 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 voltage regulators, we put ULTRA
LOW POWER voltage regulators and the consumption is only few microamps,
which enables hand-held and battery powered applications.
4.
We added Li-Ion rechargeable 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 will AUTOMATICALLY power the board – no jumpers, no switches!
5.
6.
7.
Our board has UEXT connector which allows many existing modules like
RF, ZIGBEE, GSM, GPS to be connected.
Our board has SD-MMC card for data logging.
Our board has USB-OTG hardware.
Our design allows RTC – Real Time Clock.
We made our design noise immune.
8.
9.
10.
Optionally if someone needs higher precision and temperature stability in
Analog reading we have provisioned the board with Aref precise source.
11.
The LEDs and the BUTTONs are on the edge of the board so that there is
easy access even if the boards have shields mounted.
12.
All components are LOWER than the connectors, so the shields do not in-
terfere with them.
13.
Mini USB connector is used which is common and used in most cell phones,
so you do not have to buy other cables.
14.
Original Arduino design had flaw and the connectors were not spaced at
0.1" thus making the usage of proto boards impossible, to keep the compatibility we
have same spacing but we also added next to it a connector with 0.1" step which
customers can use with perforated boards.
15.
All signals on the connectors are printed on the top and on the bottom of
the board, so when you check with probe you know exactly which port you are
measuring.

ELECTROSTATIC WARNING:
The
PIC32-PINGUINO and PIC32-PINGUINO-OTG
boards are shipped in
protective anti-static packaging. The boards must not be subject to high
electrostatic potentials. General practice for working with static sensitive devices
should be applied when working with these boards.
BOARD USE REQUIREMENTS:
Cables:
Mini USB cable
For programming via ICSP connector you will need PIC-ICSP
connector and USB A-B cable for, PIC-KIT3.
Hardware:
!!!Warning!!!
Programmer/Debugger – PIC-KIT3, or other compatible
programming/debugging tool.
PIC-ICD2, PIC-ICD2-POCKET and PIC-ICD2-TINY are not
supported nor recommended. They lack software support in
newer MPLABs
MAIN DIFFERENCES BETWEEN THE TWO BOARDS:
There are two major differences between PIC32-PINGUINO and PIC32-
PINGUINO-OTG:
1. The type of the USB connector is different (mini USB vs mini USB OTG).
The main difference between PIC32-PINGUINO and PIC32-PINGUINO-OTG is the
USB connector. The first board has a standard USB connector that is configured as
a device which allows the board to communicate only with hosts. The PIC32-
PINGUINO-OTG can be configured either as a device or a host – which allows the
board to communicate with devices also – e.g. USB smartphones, keyboards, mice
etc.
2. PIC32-PINGUINO lacks SD/MMC connector placed
Only PIC32-PINGUINO-OTG has a SD/MMC connector at the bottom. Note that
in the design of PIC32-PINGUINO not only the connector is missing but also the
other components required. For better understanding compare the schematics of
both boards.
