    Past LS1 Carrier board

    Past LS1 is Qseven carrier board that in addition to standard Qseven features supports additional interfaces provided by Borea Rakun LS1 Qseven module.

    Rakun LS1 module can be strictly Qseven compliant or can be configured to expose Freescale QorIQ specific interfaces. In such Rakun LS1 module configurations modified carrier board must be used to fully utilize module interfaces.
