Product Details


Fangtang GPS is a multi-mode satellite navigation and positioning module that supports satellite positioning systems such as BeiDou 3rd generation/GPS/GLONASS, and supports multi-system joint positioning and single-system independent positioning modules. It is based on a highly sensitive positioning chip, which can provide accurate positioning information and is suitable for various positioning applications, such as in-vehicle navigation, IoT device tracking, etc. The module adopts an integrated RF baseband design, integrating DC/DC, LDO, RF front end, low-power application processor, RAM, Flash storage, RTC and power management, which can be powered by button battery or farad capacitor to RTC, backup RAM to reduce the first positioning time, can be widely used in vehicle positioning and navigation equipment, high-precision timing, safety monitoring, surveying and mapping, precision agriculture and other fields that require navigation/positioning/timing.

Hardware Features

  1. Dual-mode positioning: Supports simultaneous use of GPS and Beidou satellite systems for positioning, providing stronger positioning coverage and accuracy.
  2. High sensitivity: Has a high-sensitivity positioning chip, which can quickly obtain positioning signals in complex environments.

Applicable fields

In-vehicle navigation, tracking of IoT devices, location-based services, etc.

Usage on Futureboard Lite


Using Futureboard Lite as an example, obtain longitude and latitude information via GPS module

Hardware Wiring:

The communication interface of the GPS module is a serial port, thus it is connected to the UART0 interface of Futureboard Lite image.png Software Programming:

  • Open Kittenblock, select Futureboard Lite as the hardware, and connect the serial port image-20240315123103539

Frequently Asked Questions


Q: Why can the GPS module not be used indoors? A: The GPS module needs to receive satellite signals, and can only receive signals in open outdoor spaces. Q: Where else can the GPS module be used besides for positioning? A: The GPS module can provide latitude and longitude information, as well as UTC time and altitude information. Q: What is the positioning accuracy of the GPS module? A: 2 meters Q: Can the GPS module display a positioning map on the screen of the motherboard? A: No, the performance is insufficient. Special hardware and software are required to achieve this positioning effect.
