The M7Plus (M7+) SBC from Novasom Industries is soft- and hardware compatible with any M7 and RP3. Based on the Rockchip RK3328 the M7+ can drive 4K UHD displays, comes with USB 3.0/2.0 and supports Linux and Android. Next to the full size HDMI connector the M7+ also provides the HDMI on a FCC connector.
Thanks to the RASPMOOD approach the M7+ can turn your Pi3 application into a fully functional industrial solution. The specific GPIO mapping library is the only thing you need to include in your Pi3 SW, in order to make it run with Armbian-Debian without any trouble.
Several development tools are available to help with the design of your application. These tools provide everything required out of the box to start you M7+ solution on day one.
