BK1511(GNSS Single Chip)

BK1511 is a highly integrated GNSS receiver providing high performance and low power consumption operation in a low-cost application. Also it supports three reception modes, which are the single GPS reception, the simultaneous GPS and BEIDOU dual reception, and the simultaneous GPS and GLONASS dual reception. The Single GPS reception does not need the external flash, but the other receptions need the external flash. BK1511 integrates a GNSS RF front-end and a baseband processor. It can support a wide range of reference frequencies and very low external component count. The simple UART serial interface and the standard NMEA-0183 protocol make usage of BK1511 very easy and straightforward. The BK1511 is available in 40-pin 5x5 mm QFN packages.
