Forlinx Embedded Technology, the Chinese company behind Linux-friendly SBCs such as the Texas Instruments (TI) Sitara AM3354 based OK335xS-II and the Forlinx i.MX6 SBC, has posted details on a new OK5718-C SBC. Like the OK335xS-II, it’s a Sitara based board, in this case tapping TI’s single-core, Cortex-A15 based Sitara AM5718. Like the i.MX6 SBC, it’s a sandwich-style offering, with the separately available FET5718-C module hosting the up to 1.5GHz AM5718.
The FET5718-C module’s Sitara AM5718 SoC may have a somewhat old-school CPU, but it provides plenty of extras. You get both a PowerVR SGX544 3D GPU and Vivante GC320 2D GPU, as well as a 750MHz TI DSP-C66X digital signal processor and video accelerator. There’s also the same, 200MHz programmable PRU subsystem found on the BeagleBone, as well as dual, 213MHz Cortex-M4 microcontrollers.
The combination of the DSP with the real-time MCUs enables robotics, machine vision, medical imaging, automotive, and facial recognition applications. Industrial automation and building automation applications are also supported.
The FET5718-C module adds 1GB DDR3L, 8GB eMMC, a TPS659162RGZR power management unit, and a 3-port Gigabit Ethernet switch subsystem. The 12-layer, 70 x 50mm COM runs on 5V power and has a 320-pin board-to-board connector.
The 4-layer, 190 x 130mm OK5718-C baseboard expands upon the FET5718-C features with ports popping out on all sides. The board provides 2x GbE ports, onboard WiFi and Bluetooth, and a mini-PCIe slot with optional 3G/4G. There are single USB 3.0 host and micro-USB 2.0 device ports and a pair of USB 2.0 host ports.
The OK5718-C is further equipped with an HDMI port, an SD slot, a CAN port, and dual audio jacks. Onboard I/O includes SATA 2.0 with power, DVP and 2x MIPI-CSI camera interfaces, and other I/O as detailed below.
