OK335xS Single Board Computer

OK335xS single board computer(SBC) integrates with TI AM335x processor and is the most simple and stable industrial development platform. Its main frequency reaches up to 800MHz, operating temp ranges from -40℃ to +85℃. And it support many industrial bus, such as: CAN, PROFIBUS, RS485, etc, support two gigabyte Ethernet port, 324-pin CPU module, each pin is multiplexed with up to 8 configured functions. FET335xS CPU modules have 512M DDR3 RAM and 256M Nandflash on it, could greatly help users to reduce the cost of product development.

OK335xS development board is specially designed for the industrial application, so RS485, CAN, and RS282 interfaces are available on the board for selection. Users could fully use PIN MUX to define functions on the base board. All boards must pass strict EMC/EMI test before leaving factory, could be directly applied into product manufacture.

Main Features Of OK335xS Single-board Computer

  • 1x RGB display, 1x UART,
  • 1x phone, 1x Mic, 1x Line in;
  • 2x 1000Mbps adaptive;
  • 3x RS232, 1x RS485
  • 4x USB2.0 Host, 1x USB2.0 OTG;
  • ...

Stable Stamp Hole Connection

The core plate and the base plate are welded with a 1.27mm space between the stamp holes, which has the advantages of anti-seismic, antioxidant, anti-jamming and low cost;
