The GP-3 is a low-cost very versatile interface that connects your PC to the outside analog and digital world. You can use this board in two different ways. First, you can connect it to your PC via an RS232 port or a USB port and use the programming language of your choice to sense and control the real world. The GP-3 supports just about any language or operating system. AWC provides libraries for Visual Basic, Visual C++, C#, Windows Scripting Host, Delphi, Java, and generic source code libraries that will work with Linux or just about any other operating system. You can also use our free prewritten software to plot analog values or do basic data acquisition. Even better, you can use our revolutionary GP3EZ system to create many common types of embedded applications with no programming whatsoever. You simply point and click and build your application. You have to see this tool in action to appreciate it, so you might want to check out the demonstration video.You can even use a GP3 to remotely control and sense things over a LAN or the Internet!
If you use GP3EZ, there is another way you can use the GP3. You can do your development using this easy to use tool. If you obey certain rules, you can then have GP3EZ program the GP-3 board with your application. Then it will run without being connected to the PC! Suppose you are using the GP3 to sequence some lights for a holiday display. You can easily modify the sequence and timing on the PC until you have it the way you'd like. Then you can program the GP-3 and it will carry out your commands without the PC. It will continue to do this until you reprogram it with a new program. Of course, you can still use it connected to the PC anytime you like. This brings a new level of affordability to embedded projects.
The GP-3 has an impressive slate of features including:
This versatile kit can be customized to use different power supplies or customized I/O. Imagine the power of real world I/O in your next project. Here are just a few ideas:
The GP-3 has found applications in model rocketry, security systems, holiday and museum displays, factory automation, solar power monitoring, ham radio, and automated test set ups. Anywhere you need analog and digital I/O, the GP-3 is a powerful and economical answer.
You can find all the software and documentation for the GP-3 in the GP-3 Center.
All you supply is a cable to the computer (a standard serial cable or a USB serial port -- you can order them as options or use your own; the GP-3U is a GP-3X board with a built in USB port in which case you need a standard mini-USB cable) and a DC power supply or 9 volt battery. The GP-3 has an onboard 5V regulator, or you can supply 5V regulated directly to it.
This kit is available in three forms (see the pictures at the top of this page). The board on the left is based on the GPMPU28 board and the one on the right is based on the GPMPU40 board. The center board is the GP-3X base board. All of these boards have the same function but differ in the accessories and how you hook things up to them.
All the GP3 boards have pins on either .2" (GP-3X) or .1" (all others) spacing. You can easily connect these to prototype boards to get more space. We especially recommend using our PROTO1 board as "wings" (see photo above that shows two wings installed). You can add one to either side of the board or add two to maximize the space for custom circuitry. The hole pattern is handy (see photo) and will allow you to add ICs, relays, sensors, or anything else you need to use your GP3. If you plan to use wings, you'll probably want to order the board without screw terminals unless you intend to mount the screw terminals on the wings.
Exactly which kit you need depends on what you want. If you want to plug the board into a solderless breadboard the GP-3 or GP-3B are easiest. The GP-3 allows you to select 9 signals and send them to the breadboard (the rest are available, but not on the breadboard). The GP-3B brings all pins out to the breadboard. The GP3-X (and GP3-XU) can plug into a breadboard but since it has pins on each side, it isn't always as convenient. However, as an option you can get the GP-3X with screw terminals which makes hooking things up without a solderless breadboard much easier.
Please note that this is a kit and does require soldering and basic electronic tools (unless you buy an assembled version). This allows you to customize the board to fit your needs. All the parts are through hole, and the solder masked board is very easy to assemble.
