K1511 (Global Navigation Satellite System Signal Chip)
BK1511 is a highly integrated GNSS receiver that provides high performance in low-cost and low-power operating applications. Supports three reception methods: 1. Single GPS reception; 2. Simultaneously GPS and BeiDou dual-mode; 3. Supports both GPS and GLONASS dual-mode, with no external flash required for single GPS reception, but other dual-mode devices require external flash. BK1511 integrates GNSS RF front-end and baseband processor, supporting a wide reference frequency and very few external devices. The simple UART serial interface and standard NMEA-0183 protocol make BK1511 applications very convenient and fast. The packaging form of BK1511 is: 40 pin, QFN5 × 5.
