So you obviously stopped production of pcDuino 3B. I asked you in March 2017 (see 4 posts below) and you did not really answer, you wrote it was available via ebay and Amazon. And now nothing available any more. Nowhere
DO YOU THINK IT IS FAIR STOPPING A PRODUCT WITHOUT ANY INFORMATION?
There are people who invested lots of time and money to develop projects with your products and you just quit manufacturing without any notice.
Linksprite is a great disappointment for me and the way you behave will make people stop using products from small an innovative manufacturers.
