DoubleWide ExtenderShield X

The other DoubleWide ExtenderShield let anyone connect two shields to an Arduino. That was fine when dealing with just one row of digital I/O. But now that there are more and more people using the Illuminato, why not pin out all the extra rows of I/O in a replicating shield as well?

Enter the ExtenderShield X Edition. The “X” stands for “eXtended”, and it means there’s now twice the pins pinned out. The left side is a pass-through replication of the right side, so there’s plenty of wire-up space on either side.

Specifications

• 4.2in tall x 2.7in wide
• 108mm tall x 69mm wide
• Arduino and Illuminato replicated mounting holes
• Arduino and Illuminato replicated plated through-holes
• Solderable dev area

Made possible by the Open Source Hardware Bank

Normally, this shield would cost someone about $70-80 apiece to make even just 1 of them. It doesn’t even start to get reasonable (for me personally) until about 25 are made. So the Open Source Hardware Bank is going to fund building twice however many are made.

In the meantime, if 50 of these get pre-bought or built by May 3rd (you can keep track by going here), then I’ll use the money to build them. If not enough are pre-built by May 3rd, Mike and I will refund the Paypal transaction. -Buy 1 – a plain old “pre-order” for 1 DoubleWide X (at cost + 15% margin)

-Buy 1, Build 1 – pre-order 1 DoubleWide X, plus fund the production (at cost) of one more that gets resold. When it sells, I’ll send you the money for that DoubleWide X, which includes cost +15% margin. So it’s like getting one DoubleWide X at cost.

-Buy 1, Build 2 – pre-order 1 DoubleWide X, plus fund the production (at cost) of two more that get resold. When the two sell, I’ll send you the money for those DoubleWide X, which includes cost +15% margin. It’s like getting one DoubleWide X at cost, and then an additional 15%, which should cover the cost shipping to most places in the US.

-Buy 1, Build 3 – This is the same as Buy 1-Build 2, except with 3 builds. This was made a popular request for guys over seas who wanted to be able to offset shipping a little more.
