Sorry, I only know connetcors and can't help you. Good luck!
RIoT Board is quite old and Has a Rather Narrow or almost non Existent Community. If you are interested in IMX6 Solution, I would suggest Having a look at WandBoard,
You can also go through NXP as they also offer some neat Dev Boards, Which may solve your purpose.
I am planning to purchase more than 10. But, I am not sure if this product is still supported and will manufactured. We will need more later on to give some ours customers.
I do not see recent updates and also some of the necessary accessories are already out of stock such as LVDS display, serial to usb converter. There is 14 of riot board in the stock.
It seems like it has been not updated for long time.
Are you planning to manufacture further Riot boards?
I need many IMX6 based development boards that will have long term support, if there are better alternatives please let me know.
