NEO-6M GPS Module for Arduino STM32 51

The NEO-6M GPS module is a cost-effective, straightforward positioning board widely used in custom drone builds, fixed-wing aircraft and DIY microcontroller projects. Operating on the classic u-blox 6 engine, it provides reliable basic GPS tracking for ArduPilot and INAV setups needing straightforward coordinate logging or return-to-home functionality.

Key features

• Integrated EEPROM with a backup battery to save configuration data and enable rapid hot starts.

• Included active ceramic patch antenna for strong satellite signal acquisition.

• Standard UART communication interface for easy integration with flight controllers, Arduino or STM32 platforms.

• Convenient 3V to 5V input voltage range allows direct power from standard 5V BECs.

• LED signal indicator provides immediate visual feedback of satellite lock status.

Specifications

• GNSS chipset: u-blox NEO-6M

• Input voltage: 3V to 5V

• Default baud rate: 9600 bps

• Interface: UART

• Update rate: up to 5 Hz

• Start-up time: 38 s cold start, 1 s hot start
