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:
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

Digital Signage has exploded over the last few years and is now utilized in businesses ranging from fast food restaurants for menu boards to factories for showing real time productivity analytics. The uses for digital signage is unlimited and the cost has come down to a price point that even small businesses can afford.
Gateworks has created a simple software signage solution for use on the Ventana Family of Single Board Computers. Connect the SBC to an HDMI or LCD display and point to the desired URL.
Gateworks Digital Signage Features:
Based on Android Lollipop, Optimized for 256MB Flash
Displays any local or remote URL in a full screen browser (Kiosk Mode)
Supports Hardware Acceleration for smooth playback of web content
Gateworks offers a LVDS connector on the Ventana Family of Single Board Computers to allow the connection of a LCD touchscreen display. LCD Displays are a great fit for control panel applications as well as Digital Signage. The displays work with Android, OpenEmbedded Yocto, Ubuntu and more.
The LVDS connector has all the necessary pins for the display signaling as well as I2C for touchscreen control.
Gateworks offers a 7-inch LCD Display with a PCAP Touchscreen. This display is great to get started in development as well as for production projects.
All of the cables, adapters and LCD can be found right on the Gateworks Online Shop so getting up and running is very seamless.

To get started, Gateworks has posted Pre-Built images on the Wiki page. The wiki page also documents building from source.
Gateworks has world class customer support. Part of this support includes keeping customers up to date with any changes to the single board computers that Gateworks designs and manufactures. Customers expect to be notified of any changes so they can be prepared properly.
Gateworks provides it’s Product Change Notification (PCN) service to notify the customer of any of the following:
A new revision of any standard product single board computer.
GSC Firmware Updates
Pre-Built Firmware that is shipped on standard product single board computers.
Gateworks has a page on their Wiki site dedicated to PCN notices as well as a mailing list that will automatically email any updates.
For more information and to join the mailing list, please view the PCN Wiki Site.
For customers who require revision locking, Gateworks offers a Specials program. More information can be found on the Specials Program Wiki Site.
There are many ways to stay connected to Gateworks. Gateworks recommends viewing our wiki section that describes all of the ways here.
Android is growing fast in embedded applications. The Gateworks Android Development kit is a great starting point for customers that need to get going quickly with both the hardware and software.
To aid in Android software development, Gateworks has developed an example Android application showcasing the interaction of the software with the Gateworks Android hardware. The application features support for the user GPIO, LEDs and more. An easy to use Android library is also provided which can be utilized for any custom application development.
Gateworks has documented Android Software on the following wiki pages:
OS Development – This wiki page covers items dealing with the lower level operating system. This includes items on the serial console command line such as init scripts, ADB, partitions, command line networking, LED control, GPIO control and other hardware integration.
App Development – This wiki page details the building of an Android App (APK file) independent of building the entire Android OS. Topics covered include setting up the Android Studio IDE, writing sample code for a Hello World App, as well as using an external Gateworks code library for accessing low level items through the app such as GPIOs, LEDs and more.
Gateworks Android Library – This is a library that allows easy integration to low level system items such as LEDs, GPIO, PWM and voltage and temperature.
Gateworks Android Demo App
Gateworks has used the information above to create a Gateworks Demo App that is publicly available on GitHub here. The app features a user friendly front end for controlling some hardware features on the board utilizing the GateworksUtil library. Screenshots of the app can be seen below:
