On motherboard backside, there are a Marvell 88W878S-BKB2 Avastar WLAN/Bluetooth/FM Single-Chip SoC.

Point Of Interest: On early manufactured Stock Keeping Units (mostly with release firmware such as 1.06) there is a known issue with faulty 3G sub boards. For more information on how to remedy check the errors page: C2-9693-7.

Mobile Data Modem[edit | edit source]

Qualcomm Gobi is a family of embedded mobile broadband modem products by Qualcomm. One of the more notable products that contain a Gobi modem is the PSVita, which contains a MDM6200™ (note:the MDM6600 got closer specs than the MDM6270).

The communication of the Modem appears to be PCIe, instead of the more common (Used on WWAN modems for laptops.) USB interface. So, the Vita might have PCIe available for use along with USB. In case anyone wants to try putting a mPCIe SSD in it or even hook up an external GPU to the Vita.
