BR-355S4环天SIRF 4 IV串口232电平PS2口接收器GPS定位模块GMOUSE
BR-355S4 Cable GPS with PS2 interface (SiRF Star IV )
The BR-355S4 GPS Receiver can be utilized in a variety of applications that require a magnetic mounting with waterproof configuration. With non-slip on the bottom and the compact design, the BR-355S4 is completely self-contained and waterproof. It''s incorporating the latest SiRF Star IV GPS chipset and an active patch antenna so you receive a high degree of GPS accuracy.
Combining both design and technology into an iF product design award 2006 winning GPS receiver the Globalsat BR-355S4 integrates the latest SiRFStarIV chipset into a stylish GPS mouse. This results in one of the most sensitive and accurate GPS receivers on the market today.
Typical application can include marine environments, aviation, commercial use such as fire truck, police cars and utility vehicles and buses.
