AT6668B BDS Beidou Positioning Module Single BDS Satellite Navigation Receiver 2.5m Horizontal Accuracy 10Hz Update Rate UART NMEA0183 Interface 3.3V 36.2mA for IoT Industrial Development
- AT6668B single-BDS positioning module receives Beidou satellite signals, supporting Beidou2 and Beidou3 with B1I and B1C signal standards.
- Integrated radiofrequency frontend and baseband processing engine handle satellite reception and positioning data within the module.
- A hardware anti-interference acceleration circuit supports positioning output under complex electromagnetic interference conditions.
- Horizontal positioning accuracy is 2.5m, providing a stated accuracy figure for evaluating positioning requirements.
- Position refresh reaches up to 10Hz, while cold-start time is 24 seconds according to the supplied specifications.
- The module operates at DC 3.3V with a working current of 36.2mA at 3.3V, useful for checking power requirements in a device design.
- UART serial communication outputs standard NMEA0183 location data, with a configurable baud rate from 4800bps to 115200bps.
- Operating temperature is listed as 40 to +85; the source does not specify a temperature unit.
- An external active Beidou antenna is required, and an open-sky environment is needed for good satellite lock-on performance.
- The package contains 1 AT6668B Beidou positioning module; basic embedded debugging experience is needed for configuration and development.

Product Description:
AT6668B is a single-BDS satellite positioning and navigation module that receives BeiDou signals for IoT terminals, industrial positioning, and outdoor navigation.
Core Selling Points:
Supports BeiDou-2 and BeiDou-3 with B1I and B1C signals. The integrated radiofrequency frontend, baseband processing engine, and hardware anti-interference circuit support stable positioning output in complex electromagnetic environments. Low-power design suits battery-operated field devices.
Technical Specifications:
Model: AT6668B. Positioning accuracy: 2.5 m horizontal. Maximum update rate: 10 Hz. Cold-start time: 24 seconds. Working voltage: DC 3.3 V. Working current: 36.2 mA at 3.3 V. Interface: UART serial. Protocol: NMEA0183. Configurable baud rate: 4800 bps to 115200 bps. Operating temperature: 40 to +85.
Package Contents:
1 AT6668B BeiDou positioning module.
Before Purchase:
Requires an external active BeiDou antenna. An open-sky environment is required for good satellite lock; poor antenna installation or sheltered surroundings may cause positioning failure. Basic embedded debugging experience is recommended.
