I bought 12 ST EDU boards to replace the Board of Education from Parallax in the Boe Bot for my class that learned PBasic and now they will learn "C".
The boards work perfect and they high quality and one of the things I like the most is the circuitry they have for using two rechargeable 18650 batteries.
The boards fit perfectly into our boebots and they are pretty cool.
