1. Product overview
1.1 Production introduction
E108-GN01 is a high-performance, highly integrated, low-power, low-cost
multi-mode satellite positioning and navigation chip. It can be used for GNSS
positioning applications such as car navigation, smart wearable, and drone. It also
provides software and hardware interfaces compatible with other module manufacturers,
which greatly reduces the user's development cycle and supports BDS / GPS /
GLONASS / GALILEO / QZSS / SBAS.
It adopts the integrated design of RF baseband, integrates DC / DC, LDO, RF front-end, low-power application
processor, RAM, Flash storage, RTC, and power management, etc. It supports crystal or external pin clock input. A coin
cell battery or a farad capacitor supplies power to the RTC and backup RAM to reduce the time to first fix. It also
supports multiple ways to connect with other peripherals, such as UART, I2C, SPI or GPIO.
