As a response to the overwhelming storm of interest on using AYAB by the knitting machine community and other curious folks, we decided to produce and sell a small batch of pre-soldered and tested AYAB Shields for Arduino. There is not profit for us by selling those shields (in fact, it's a lot of work to solder such a bunch of shields), but we wanted to enable also people which are not into soldering to try our hack with their (newly bought) machine :)
