"READY. This is the new version of Electronic Brick Shield. We standardize all the connectors into 4 pins(Signal 1,Singal 2,VCC and GND) 2mm connectors, which simplify the wiring of electronics projects. The 4pins buckled connectors also make the wiring situation more stable. We build all kinds of Twigs to match up with Stem, still don't you need to worry about the compatibleness between stem and your existing Electronic Bricks.We have many kinks of converter cables(still increasing) to deal with the compatibleness.This is very similar in fashion to an Arduino shield board, and in fact is used as such with our Seeeduino or Mega boardIn v1.0b, we move in the analog connectors a little so that it will fit the higher power connector and USB connector.
Base Shield is compatible with Seeeduino or Arduino UNO and Duemilanove."
