BU-1315 module is a high sensitivity, low power consumption and very compact surface mount device (SMD), L1 band signal that it supports, such as GPS C / A signal processing and global navigation satellite systems (including WAAS, EGNOS, and MSAS). Global Positioning System which 56 channels (GPS) receiver is designed for a wide range of OEM applications and based on fast deep GPS signal search function. The bu1315 is designed to allow quick and easy integration into GPS-related applications, especially in the compact size of the device, such as: PDAs, handheld computers and other computing devices, fleet management, asset tracking, location-based services and AVL handheld personal locator The navigation device 1. Features of hardware and software acquisition channel 56, to achieve 162dbm track easily integrated compact module size: 15x13.0x2.5 mm. SMT pads allow fully automated assembly process equipment and reflow built-in LDO regulator to reduce BOM cost extra to 10Hz update rate embedded DC / DC circuits extend battery life performance AGPS support cold / warm / hot start time: 30/29/1. RF Metal Shield for best performance in noisy environments enhanced navigation performance interface TTL level UART interface NMEA protocol: Baud rate: 9600 bps (default), the advantages of compact size of the device ideal for data / power / RF surface mount pad through flexible and cost-effective hardware design different application requirements to install the security patch method of PCB
