Product Description
The UAM2 is probably the neatest audio kit to come along in quite a while! It uses the latest amplifier technology to bring you clear, crisp, high-power audio without any of the heat which is normally generated! This is what is called a class "D" amplifier, or as the media calls it, a "Digital" amplifier. Instead of operating like a classic class "A" or class "AB" amplifier which leaves transistors biased on all the time, losing energy whether they are producing audio or not, the class "D" amplifier only produces power into the load or your speaker! This means that a small SMT part can deliver a full 20 watts of power without getting so much as warm! YES, I said SMT or Surface Mount! Now you can install this amplifier right inside your speaker enclosures, or wherever this nifty kit will fit, without worrying about a heatsink! Just look at the specs! Unique board can be snapped out into a small circle to be double face tape mounted directly to the back of a speaker! This IS a Surface Mount (SMT) kit, so you will need fine tweezers, magnifier, and a decent fine tip soldering iron! See assorted tools and accessories on our site. If you need a good 18VDC power source, check out our SPS18 power supply. (Who ever thought of 20 watts in a single SMT device; I still remember fighting with vacuum tubes to get 20 watts!)

Motorola i880 Phone (Nextel) Manufacturer: Motorola Product Group: Wireless Binding: Wireless Phone ASIN: B000KI2UYG 2006-11-10

Amazon.com Product Description

<B>Design</B>
The i880 is no ordinary clamshell. Like other Nextel phones, it's built tough for construction and utilities industry users. The phone sports a very large 176 x 220 TFT color display with a stunning 262,000 colors. Meanwhile, the outside cover features a supplementary color screen that can display images, time, call information, battery and signal strength, and more. The built-in camera and LED flash are located above this display, while media control keys for the built-in MP3 player are arranged below the display.

A speakerphone unit is located on the rear of the phone, while the trademark Direct Connect and menu scrolling functions can be controlled from the side of the phone. The phone's control pad also features a five-way button that can control most of the phone's functions. A small button on the hinge of the phone's flip mechanism automatically opens the phone for quick access--a real plus if you have your hands full. A standard headset jack is also provided. As mentioned, the i880 also sports a slot for a microSD memory card.

<B>Calling Features</B>
The i880's built-in address book can store up to 600 contacts for quick and easy management of phone numbers and email addresses. The phone comes with built-in polyphonic ringtones plus a vibrating alert. More polyphonic ringtones can be added, as can MP3-based ringtones. Voice activated dialing makes calling your friends, family, and associates as easy as saying their names. You can also speak numbers and control other phone features with the sound of your voice. A built-in speakerphone makes it easy to talk without having the phone to your ear, and because the i880 is Bluetooth enabled, you can use it with a wide assortment of Bluetooth headsets for hands-free conversations. The i880's GPS location technology pinpoints your exact location when you dial 911.

The i880's included GPS feature can come in handy in situations other than emergencies as well. Whether you need turn-by-turn driving directions or a smarter way to manage your mobile travel needs, Nextel's Global Positioning Satellite (GPS) solutions can help get it done. Enjoy audible and visual turn-by-turn driving directions to any address, anywhere on Nextel's Nationwide Network, or, use GPS location-based safety services like Mobile Locator, a feature that allows you to locate a friend or family member's phone location at anytime, right from your computer (both require a subscription). And of course, if you need to make a 911 emergency call, the GPS feature can also help emergency personnel locate you. (If your phone has adequate access to GPS satellite signals and the emergency response center is equipped to process such information.)

One of the key features of any Nextel phone is support for Nextel's Direct Connect walkie-talkie technology. The i880 fully supports the service, which allows for one-touch conversations with anyone else on a Nextel phone. It's like a having a CB radio with enough range to cover all of North America, and even across borders to Latin America and Canada.

With the i880's powerful Direct Talk function you can also communicate in walkie-talkie mode when you're not even connected to the network. The system works anywhere, anytime between compatible phones within a range of up to 6 miles (range will vary based on terrain and conditions). Direct Talk provides a reliable back-up communications tool in times of emergency, network outage, or when traveling to remote areas not under Nextel coverage such as hiking, cruise vacations, or inside buildings.

The i880 also features a walkie-talkie private speaker button. This switches from the external speaker to the earpiece for private conversations or to minimize disruptions in quiet environments.

<B>Messaging, Internet, and Tools</B>
The i880 features MMS-based support for mobile-to-mobile or mobile-to-email text and photo messaging. When used in combination with the phone's built-in camera, MMS opens up a whole new world of messaging fun. T9 text entry, which is a technology that makes it easier for people to enter words and text on handsets, is built into the unit--a plus for mobile email and text messaging users.

Getting on the Internet anywhere is easy with the i880, as well. Nextel's optional data packages allow you to read and send e-mails, exchange instant messages, and view your favorite web content on your phone. The service also features games, ringtones, real-time news and sports updates, virtual address books, and more--all delivered to your Nextel phone. With a Nextel Data Unlimited pack, you can get unlimited data transfers from the Nextel network--great for those times when you want to connect your laptop or PDA to your i880 via Bluetooth and surf the Web or check your email.

Another Nextel innovation supported by the i880 is Nextel Direct Send. Simply push a button and instantly send all your contact info to another Nextel phone. It's an easy way to get people into your contact list fast.

The i880 ships with a calendar, a clock, and a voice recorder.

<B>Imaging and Entertainment</B>
The i880's 2.0-megapixel camera features a 4x digital zoom and a built-in flash that makes it easier to get quality shots in low-light situations. The i880 can also capture video clips--capture length is only limited by the amount of available memory on the memory card. The phone's Media Center application and large internal memory (21.9 MB) allows you to store plenty of photos in a variety of file types.

Need some music on the go? The i880's got you covered. A built-in MP3 player lets you listen to tunes on your memory card wherever you please using the speakerphone, or via a pair of stereo headphones.

The i880 is compatible with a number of Java applications available from Nextel. Choose from the previously mentioned TeleNav for GPS-based audible driving directions or Mobile Locator for finding the location of a friend or loved-one's phone (both require a subscription). You can also take a break or organize your schedule with supported games or organizational applications. More game and application downloads are available from Nextel.

<B>Vital Statistics</B>
The Motorola i880 weighs 4.34 ounces and measures 3.55 x 1.97 x .97 inches. Its lithium-ion battery is rated at up to 2.8 hours of digital talk time, and up to 130 hours of digital standby time. It runs on the IDEN 800 frequency. The phone comes with a one year limited warranty.
