Last May, Forlinx launched an ARM development board to market based on NXP i.MX6Quad processor. It proved to be an excellent item according to feedback of customers from both domestic and overseas markets.
But what is a problem is that this item is a high configuration board compared with the past products, and some customers think the price is a little expensive, thus we consider to simplify the base board to reduce cost.
