     1= Ventana SBC Without PCIe Switch =
     2
     3Nearly all of the Ventana SBC boards have a PCIe switch which takes a single PCIe signal and expands it to the multiple Mini-PCIe slots on the boards. This is a very unique feature which allows for multiple wireless radios to be used.
     4
     5For designs that do not require multiple slots that support PCIe, this switch can be removed and the cost reduced.
     6
     7== GW5220 ==
     8The GW5220 is based on the GW5200 baseboard but without the PCIe Switch.
     9
     10What this means is that only one slot can have a Wireless Mini-PCIe radio. Only one slot has PCIe routing. The other slot has other signalling, such as USB.
     11
     12The GW5220 has two Mini-PCIe slots like the GW5200, but they are described by the following:
     13
     14'''Mini-PCIe J7'''
     151. Optional PCIe - default is PCIe routed to J8 connector.
     162. USB Host port
     173. SIM socket mapped to socket to support cellular modems
     18
     19'''Mini-PCIe J8'''
     201. PCIe or mSATA  – One or the other can be selected through a software controlled buffer. Default is PCIe.
     21 1. *Note: mSATA available on Quad Core models only
     222. USB OTG optional – controlled through software switch. Default is USB OTG to front panel connector.
     23
     24Additionally, the GW5220 supports SPI which other boards do not expose.
