Are any of the older Luxonis modules completely open hardware?

I see most of the carrier boards are open hardware, but the SOM that makes them function appears closed-source hardware?

    Hi @sam_uk ,
    Yes, carrier boards (for SOM) are open source, SOM (more precisely all chip-down designed PCBAs) and firmware are the only 2 closed-source items; that's our core IP and core of our business model (how we make money).
    Thanks, Erik
