SBC-C20 – SBC with NXP i.MX 8M Applications Processors in 3.5” form factor


SBC-C20 is an SBC built upon the NXP i.MX 8M Application Processors characterized by HEVC/VP9 decoding in 4Kp60 as well as HDR. As for the memory, it features a DDR3L RAM. Moreover, it provides an optimized IoT stack with preinstalled Wind River Linux 10. The range of connectivity options is particularly broad, with optional Wi-Fi and BT LE 4.2 module, M.2 socket 2 Key B for WWAN modules. Interestingly, it also features a Cortex-M4 for RTOS, the real-time operating system for serving real-time applications that process data as it comes in without buffer delays.
