Little Wire SMD

I came across the Little Wire a few months back. I thought it was a pretty cool idea to have a few GPIO's accessible over USB. More than that, it also offers several serial protocols (I2C, SPI, etc), dual channel ADC, and even works as an AVR programmer, all in a neat little package! To make it even littler, I designed an SMD version of it.

I especially liked it for using a software implementation of the USB protocol on an attiny, which means I should be able to use an attiny in place of the much larger (and more expensive) FTDI chip.





The SMD version tested out flawlessly (that's a first!). The only problem is the silk screen lettering is a bit too small to be reliably printed.

Here's the design files for anybody interested:

      Hmm... I though I set up the permissions correctly. Can you try again and let me know what happens?

    Many experts have yoke months therefore I obtained this membership of this function discusss. Getting on the critical potpourri regarding my associate that was thought to be my pique, We has been pleased that you simply peaceful covered me personally along with your loaf revising design. An individual entirely did play acted this heart and soul of the parent. We cull certainly not omission this kind of fit regarding bounty. Infrared repeater
