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 Programmer Debugger PIC KIT3 or other compatible programming debugging tool Warning 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 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 Page 4 SCHEMATICS PIC32 PINGUINO

OUPIEX PIC32 PINGUINO and PIC32 PINGUINO OTG development boards user s manual All boards produced by Olimex are ROHS compliant Revision E October 2013 Designed by OLIMEX Ltd 2011 Page 1 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 Pro cessing based IDE The project began in Ivrea Italy in 2005 to make a device for controlling stu dent built interaction design projects less expensively than other prototyping sys tems 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 pro ject 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

18. 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 pro ject 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 currently the IDE which have GCC in background can support 8 bit PIC microcontrollers 32bit PIC32 MIPS microcontrollers and ARM7 CORTEXM3 microcontrollers which makes PINGUINO very flexible as once you make your proje
