OpenEmbed SOM9331 v1
The SOM9331 is a Single Board Computer (SBC) with 8MiB of NOR flash and 64MiB of ram. It is made by the Chinese manufacturer OpenEmbed and comes in two form factors: a System on Module (SOM) with castellated pins, and an SBC with the hardware peripherals broken out; including 3x100Mb Ethernet ports, USB to UART for debug and a USB Host. SOM9331 Ships with OpenWrt 12.09 Attitude Adjustment.

Opening the case
This board does not come in a package, it only comes with a plastic base separated by copper spacers and screwed together. Therefore it is really easy to take it apart.
All you will need is a Phillips head screw driver.
Use the following steps to remove the base:
- Remove the four screws from the top of the device, using your Phillips head screwdriver.
- Remove the plastic casing from the bottom.
You now have access to the front and back of the pcb.
