DFRobot GPS + BDS BeiDou Dual Module

This small positioning and navigation module from DFRobot is based on the AT6558 (a six-in-one multi-mode satellite navigation and positioning chip). It can provide real-time location information and supports a variety of satellite navigation systems, including up to 32 tracking channels. Additionally, the module can receive GNSS signals from six different satellite navigation systems simultaneously, including the Chinese BDS, American GPS, Russian GLONASS, European GALILEO, Japanese QZSS, and the SBAS Satellite Augmentation System (WAAS, EGNOS, GAGAN MSAS), to perform accurate positioning and timing. The error of the positioning accuracy is under 3m, which is comparable to the accuracy of a smartphone. The power consumption of the module is less than 0.1W and can thus operate continuously for a long time with a small power supply. Due to the small dimensions of the module, it can be embedded in various types of drones and smart cars.

In serial output mode, the AT6558 is compatible with various mainboards equipped with a serial output: 

• Arduino
• Raspberry Pi
• STM32
• ESP32
• EP8266
