SBC-C23

From WIKI SECO
SECO SBC-C23

The SYS-C23 is a Smart Edge Compute Unit, built on NXP i. MX 6SoloX Processor, enables multi core edge computing and networking, while ensuring wide connectivity. As far as memory is concerned, the device features a 32-bit DDR3L memory soldered on-board, up to 1 GB. When it comes to interfaces the board is plentiful: networking interfaces - such as 2x Fast Ethernet RJ-45 ports, Wifi, BT LE combo module with on-board antenna - but also other interfaces like 2x CAN port, 4x analog inputs, I2C, 2x PWM and many others. The device is indeed a multiprotocol bridging for industrial PLCs and smart factory devices. Fields of application include Home Automation, Industrial Internet of Things and Surveillance among the many.
