Gravity: GNSS GPS BeiDou Receiver Module

The GNSS receiver module supports multiple satellite systems for accurate, high-speed positioning in various environments. It’s compatible with I2C/UART devices. GNSS stands for Global Navigation Satellite System. The main GNSS systems include GPS, GLONASS, QZSS, and BeiDou. These satellite systems transmit signals to the earth, allowing the receiver to determine its own position by calculating the propagation time of the signals and the position of the receiving satellite, thus achieving functions such as positioning and navigation.

Gravity: I2C SD2405 RTC Module

The I2C SD2405 RTC module features accurate real-time clock, dual power supply, low power consumption, periodic interrupts, and a high precision time trimming circuit. The SD2405AL is dual power supply system. When the primary power supply goes down to an assigned value or resumes from low power, the system can switch between the primary power supply and battery automatically. Even there is no external power, it can still work for 5~8 years, 1uA ultra-low power consumption.
