Based on the GPS L70 module from Quectel®, the Xadow GPS v2 combines the advanced AGPS technology EASYTM (Embedded Assist System) and the AlwaysLocateTM technology to achieve high performance, ultra-low power consumption and fast positioning even at indoor signal levels. With an excellent high-sensibility receiver (-163dBm tracking) and a built-in chip antenna, the module can track up to 22 satellites on 66 channels, making it a perfect choice for navigation projects. The board also adopts the new 11 PIN Xadow connector to improve the flexibility of module connections.

Global Positioning System (GPS)

The Global Positioning System (GPS) is a space-based navigation system that provides real-time and all-weather geographic position, altitude, travelling speed and time information anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It was formerly used only by military projects, now it is freely accessible to anyone with a GPS receiver. The typical applications of GPS covers automobile navigation, time transfer, traffic signal timing, anti-theft and tracking devices etc.

You need a WiFi Internet connection, and a smartphone or tablet for the Echo App. That's it. It is easy to set up, but it may take you a while to figure out all of the little things that the Echo App can do.

BEWARE this is NOT STEREO and it is NOT MONO. This is only one channel. You will not hear part's of songs (recorded in stereo) that are only played through the left channel. Kinda ridiculous. Still it is a decent sounding speaker.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
