I have (and use from Arduino IDE with UNO) the V1 motor shield for DC motor controll of a large toy crane to measure sensor characteristics.
Much cheaper than V2. https://learn.adafruit.com/adafruit-motor-shield/downloads
The lib converted to B4R would be welcome.
I placed my order and I will get Adafruit MotorShield V2 this week. I will post the result.
With V2 you can control more than one shield and can connect >2 Step-Motors
Today I got my Adafruit Motor Shield V2.
At the picture which is enclosed you see upside Board V1 and downside Board V2. These both are not compatible.
Inportant Message: The rAdafruitMotorShieldV2.zip works in my case without any problems.
@Erel: Thanks a lot for your help and your support. Sorry for the trouble
