Forlinx Embedded, a company based in Baoding, Hebei, China specializing in embedded systems design and manufacturing, has recently launched OK335xS-II single board computer powered by Texas Instruments AM335x SoC which they claim to be “the cheapest industrial Cortex-A8 board in history” as it sells for as low as 298 RMB or about $48.

Forlinx_OK335xS-IIOK335xS-II board is comprised of a baseboard and a CPU module soldered to the carrier board with the following specifications:

  • SoC – Texas Instruments AM335X ARM Cortex-A8 processor @ 800MHz with PowerVR SGX530 GPU
  • System Memory – 128M DDR3 + micro SD slot
  • Storage – 256MB SLC NAND Flash
  • Display I/F – LCD interface with support for LCD to LVDS and LCD to VGA, and resistive touchscreen interface
  • Connectivity – 1x 100M Ethernet
  • USB – 1x USB 2.0 host, 1x mini USB 2.0 device
  • Serial – 5x serial port (1x debug interface, 4x TTL port)
  • Expansions headers – 5 headers with access to
    • 7x AD (2x for user, 1x for slide rheostat, 4x for resistive touch)
    • 1x I2C, 1x SPI
    • 1x I2S
    • 2x CAN
    • 3x PWM(1x backlight, 1x buzzer, 1x user expansion)
    • 8x GPIOs
  • Misc – 2x LEDs, 3x user keys, boot and reset key, boot switch, battery for external RTC chip
  • Power Supply – 5V
  • Dimensions – 52 x 42mm (CPU module); 104.2 x 81 mm (Baseboard)
  • Operating Temperature Range – -40℃ to +85 ℃
  • Relative Humidity – 10%~90%

The company can provide 4.3”, 5”, 7”, 8”, and 10.4” LCD display to work with the board, Wi-Fi can be added via SDIO or USB, and the boot switch is used to select between NAND or SD card boot.
Both Linux 3.2 (Arago?) and Win CE6.0 are supported, and the board apparently sells pre-loaded with Linux 3.2. There’s supposed to be “abundant documentation” with Linux and WinCE software manual, a Qt development guide, and various sample programs. None of the documentation and source code are available online, so that’s something you’d get when you purchase the board.

You can find a little more information on Forlinx OK335xS-II product page.

Thanks to Nanik for the tip.

What can people like you and me use this board for


I don’t see many industrial features – 24V is standard there but this one support 5V only (barrel style connector for “industrial”?)
They have 3 modules with AM3354 which gives 3D accelerator but drops the PRU-ICSS. I doubt industrial devices needs 3D as much as real time subsystem.
But still it is nice to see modules that are “DIY-friendly” (in sense of module to baseboard connectors, or solder points).


Here I can buy for 298Y

It looks like they are here in Shenzhen too…
