SiRF V GPS/GNSS模組 Ct-G551 GPS/GNSS接收模組
產品型號：Ct-G551
產品特色
The Ct-G551 GPS module is a high sensitivity, low power, Surface Mount Device (SMD) that fully utilized SiRFstarV upgraded features.
This 48-channel Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS) receiver is designed for a wide range of OEM applications and is based on the GPS signal search capabilities of the SiRFstarV CSRG05e ROM chipset, Serf’ s newest chipset technology.
The Ct-G551 provides flexible bus interfaces (UART).
