VIA unveiled a SODIMM-style COM based on its Cortex-A9 WM8850 SoC, with 512MB RAM and 8GB eMMC, plus Ethernet, CSI, graphics, USB, and serial ports.

The 68.6 x 43mm “SOM-6X50” computer-on-module appears to be VIA’s second-ever ARM COM. Back in Sept. 2015, the company released a 70 x 70mm Qseven form factor QSM-8Q60 COM, based on a 1GHz NXP DualLite SoC.

The core of the SOM-6X50 module is VIA’s 5-year-old Wondermedia WM8x50 SoC, which is also offered in a 1.5GHz-clocked model, according to the Wondermedia Wikipedia page.

In addition to its single ARM Cortex-A9 core, the WM8850 SoC integrates a Mali-400 3D GPU with a 1080p video decoding engine capable of H.264 video encoding. The integrated graphics engine supports OpenGL ES 2.0 hardware acceleration, plus MPEG-2 and H.264 video decoding up to 1080p, says VIA.

Specifications listed for the SOM-6X50 module include:

  • Processor — VIA Wm8850 SoC
    • 1x 1.0GHz Cortex-A9 core
    • Mali-400 SP GPU with 2x independent 3D/2D GPUs
  • Memory/storage — 512MB DDR3 SDRAM; 8GB eMMC flash
  • Networking — 10/100Mbps (Realtek RTL8201)
  • Video — 1x HDMI, 1x 18/24-bit single-channel LVDS or DVO, DVI, CSI
  • Audio — line in, line out, mic in; Wolfsen WM8960 Codec
  • Other I/O — 2x USB 2.0, 1x USB 2.0 device port; 6x UART ports (5-wire); 11x GPIO; 3x I2C; 1x SDIO; 2x SPI; 4x PWM
  • Dimensions — 68.6 x 43mm (apparently 204-pin stretched SODIMM format)
  • Power — (not specified)
  • Operating temperature — 0 to 60°C
  • Operating system support — Linux, Android, and bootloader BSPs are available

VIA also offers a SOMDB1 “reference carrier board” for the SOM-6X50, for evaluation and development purposes (shown below). The board includes a WiFi/BT subsystem.

  1. Benjamin HENRION says:

    Wondermedia kernel support has always been a nightmare. I have a VIA Rock board, with an outdated 3.0 kernel from Android, a real disaster.

  2. Jayro Jones says:

    I dig the modularly-upgradable design, very cool.
