A few months ago, [Omer] sent in a Raspberry Pi to Arduino bridge (http://hackaday.com/2012/05/06/using-arduino-shields-with-the-raspberry-pi/) he’s been working on called Ponte. Now that he’s gotten a few assembled, he can actually test out his ideas (http://omer.me/2012/07/ponte-revision-0/) for combining the powerful Raspi with the ubiquitous Arduino.
Ponte revision 0 used a pair of 12-bit analog to digital converters (http://www.ti.com/product/ads1014), but during the soldering and debugging phase of development [Omer] discovered a few things were wrong with his original design. The FETs on the fabricated boards had the drain and source pins mixed up, but that problem was easily solved with a bit of board surgery.
The worst problem was the mechanical design of Ponte rev. 0 – the power jack on the Ponte is directly above the Raspi’s USB port, meaning it’s impossible to plug the Ponte into the Pi.
[Omer] is working on these problems and should have the revised boards completed shortly. A few people have asked where they can get a Ponte, but right now there are no plans to assemble and ship boards. That may change, but for now if might be worth bugging [Omer] to put his new and improved Ponte (with an 8-port I2C port expander!) up on SeeedStudio (http://www.seeedstudio.com/depot/)
