Not Quite Building A Raspi Arduino Bridge


A few months ago, [Omer] sent in a Raspberry Pi to Arduino bridge he’s been working on called Ponte. Now that he’s gotten a few assembled, he can actually test out his ideas for combining the powerful Raspi with the ubiquitous Arduino.

Ponte revision 0 used a pair of 12-bit analog to digital converters, 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

  1. This is a good example of why you should always build a circuit on protoboard or stripboard or something similar to work out the problems before doing a fabricated pcb, unless you have money to throw away.
