Peripherals connected to Single Board Computers (SBCs) require separate power, sometimes in large amounts not typically available on the SBC. Additionally, some high power wireless radios require an additional power source, such as 5V for the RF power amplifier.
Gateworks designed the GW16120 Mini-PCIe Power and USB Expansion Card to meet these power needs while eliminating the need for an additional separate external power supply. Given the robust power supply on the Gateworks SBCs, using the power from the Mini-PCIe slot can provide many watts of power dependent on the SBC. Both 3.3V and 5V rails are provided along with an additional bonus USB port. The GW16120 also allows for stacking of a Mini-PCIe wireless radio or other card on a riser connector for applications that cannot give up a full Mini-PCIe slot.
The GW16120 Provides :
- Up to 8.0W @ 3.3V (shared – see datasheet)
- Up to 6.5W @ 5.0V (shared – see datasheet)
- Additional USB 2.0 connector (for Mini-PCIe slots with USB signalling)
- Riser Mini-PCIe slot to be used by wireless radio, etc
- Power and USB Cables available
- No software required

Wireless access is everywhere and has become an essential convenience that customers expect businesses to provide. Wireless connections can become unreliable and suffer in high density use areas like trains, buses, cafes and stadiums. Users can face slow bandwidth, dropped connections and interruption when streaming video.
To improve wireless reliability, quality, and performance in high density areas, AOIFES has created a software solution called “Cognitive Hotspot Technology (CHT)” that runs on Gateworks Single Board Computers. CHT software is intelligent and designed to efficiently handle a large number of concurrent connections. Wireless access points with CHT software installed throughout a train or building can communicate with each other in real time allowing them to make intelligent decisions based on the current load and demand by the users. CHT increases throughput performance by over 400% thereby increasing the capacity of both number of simultaneous clients and the bandwidth availability for high QoS applications such as video streaming.
CHT on Gateworks SBCs provides the following advantages:
- Eliminates Bottlenecks
- Provides Advanced Load Balancing
- Increases network capacity and reliability
- Increases network speed and performance
- Reduces RF emissions, interference, and electricity consumption
- Reduces the number of needed Wireless Access Points
