-# LittleWire
-# Overview
-I can't think of anything to add to the official description of the LittleWire. For me, it's a cool tool to build, and a cool tool to have on hand, mostly for programming AVR chips...
-# Perfboard
-A while back, I used a round piece of perfboard to make a smd-like LittleWire... No schematics, it's directly inspired from the Schematic of the Little Wire. The only difference is: D+ and D- are swapped to make it easier to solder...

-It's a little bit messy, but it worked, and still does its job !
-# SMD
-I was a little bored and wanted to practice SMD soldering, just for fun. So I made an SMD version of the LittleWire.
-* Small footprint
-* MiniUSB connector
-* Easy to use header => Can be plugged in a breadboard !
-* Micronucleus bootloader
-## PCB
-I still haven't made a schematic, so please, refer to the annotated PCB to assemble the board.
-Sorry, it's a little bit crowded, but everything should fit nicely... 600 DPI image, as usual around here...
