The Ct-G431R GPS module is a high sensitivity, low power, Surface Mount Device (SMD) that
fully utilized SiRFstarIV upgrade features. This 48-channel global positioning system (GPS)
receiver is designed for a wide range of OEM applications and is based on the GPS signal
search capabilities of the SiRFstarIV GSD4e ROM chipset, SiRF’s newest chipset technology.
The Ct-G431R provides flexible bus interfaces (Optional: UART , I2C or SPI reserved for
customizing special user applications).
