Fedevel released an open source design for a Linux-ready, i.MX6-based “OpenRex” SBC with a Cortex-M3 MCU, a stackable design, and Arduino and Pi expansion.
Most embedded board vendors announce a board for pre-sale, then wait to post whatever documentation they intend to release when they finally ship the board. Slovakia-based training and embedded firm Fedevel and its manufacturing partner Voipac have taken a different tack. In conjunction with their announcement of the open source OpenRex SBC, they released full documentation for the board, including complete Altium design files with schematic & PCB plus full manufacturing documentation.
