With only 7 days left, the Shield I/O BeagleBone Black to Arduino Shield
adapter needs some support. They are looking to raise 5,000 euro and are
currently sitting just under 1,000. Read more below or at

BeagleBone Black Project Spotlight: Shield I/O
Some unlikely combinations just seem to work: Oreos and peanut butter,
Dwight Schrute and Michael Scott and now Arduino and BeagleBone Black!

With the new Shield I/O, you can now use (almost) any Arduino shield with a
BeagleBone Black. The Shield I/O, created by Andreas Behrend, adapts
Arduino shields to be BeagleBone Black compatible, it doesn't matter if
you're using 3.3V or 5V logic or up to 5V analog inputs. Precise resistor
arrays divide the analog inputs and make it an option to measure up to 5V.
Shield I/O comes with dedicated level shifters for all 14 digital GPIO
pins, PWM, I2C and SPI. Something interesting to note is that part of
Shield I/O comes from an Atmel ATTiny that lets the user switch logic
levels through software over I2C.
The device uses two TXB0108 level shifters for standard I/O lines and one
TXS0102 shifting the I2C bus. Shield I/O also comes in a "Plus" version,
which features a MCP23017 that is also accessible over the I2C bus.
Andreas saw a need for Shield I/O while working with microcontrollers that
had to be rebooted to switch between different programs or adapt to new
settings. He wanted to give developers an option for a ready-made Arduino
Shield to use with a powerful embedded device, BeagleBone Black. Shield I/O
makes it possible to communicate with Arduino shields without re-flashing
or rebooting the whole system.
Andreas chose BeagleBone Black because of its power and compatibility.
"It's the most powerful embedded device out there with enough PWM, SPI,
I²C, Timers, analog inputs, which can be muxed to fit the Arduino pin
mapping including 2 PRUs to get high speed timing wherever it's needed,"
Behrend stated.
Andreas is a student currently employed by impressx
media<http://beagleboard.us3.list-manage2.com/track/click?u=6e7c2131525b7b1b74c71e2cb&id=f942e09496&e=0f3c03e366>,
who supports the Shield I/O. Additionally, Andreas has worked as a graphic
designer and has run his own business. His next project is in the works and
will be used in the healthcare industry - a tracker used by doctors to
monitor a patient's overall health.
Just as each developer creates their own projects, the Shield I/O allows
its user to employ their own creativity and make their own projects, with
Shield I/O as its base.
