Making products with the Raspberry Pi Compute Module
Most Raspberry Pi owners are delighted with what the standard
models offer, but thegrowing appeal of turning a project into
saleable product, fuels a new need that OpenPisolves. Inventors,
Makers and Coders havent failed to notice the Pi appeal,
however
addressing these new needs requires a different approach.
OpenPi is a small, discreet and open source, wireless 32bit ARM
based computer. It is atool to help people who create software to,
prototype hardware, carry out customer
trials and undertake small scale manufacture. The growing trends
in software causedby new movements in technology, like; Wearables,
the Internet of Things and SmartCities creates a demand for new
practical tools.
Sharing many similarities to the Pi, the notable differences
are:
Being Compute based, OpenPi is more expensive in singles,however
in large quantity the price is similar.
The on-board real time clock and temperature sensor give added
functionality. Exchanging Ethernet for WiFi significantly lowers
power consumption, making it
much more flexible when installing in home or office
environments. The Pi Foundations Compute development board requires
you to install an OS
before you can use it. OpenPi is instantly usable thanks to a
pre-loadedLinux operating system.
OpenPi is about a 3rd of the cost
The design files can be downloaded and edited in EagleCAD. Using
the design as aworking platform, it is possible to quickly
repurpose OpenPi to suit many differentneeds.
When purchased as a complete kit with its wireless keyboard,
WiFi adaptor and powersupply it is as quick and easy to set up as a
games console. To start you off all versionshave pre-loaded
Minecraft and a number of useful programming utilities
including:
Arduino IDE, Putty, RASWIK files, LLAP+ beta software, MONO,
Python and Scratch.
Programming languages supported include: Java, C, C++, C#,
Visual Basic, Python,Scratch, PHP, Ruby, (and many more!)
The on board SRF transceiver provides connectivity to Wireless
Things sensors andtransceivers. There are 17 general purpose I/O
pins, including; SPI, I2C and Serial.OpenPi could be used for:
Wi-Fi server Internet of Things hub HD media player
Central heating controller Games Console Bluetooth iBeacon
Security system...and much more
The injection moulded case which accompanies OpenPi can be
branded with your logomoulded into the case front*
