Description
The NEO-6M GPS Module is one of the most widely used and reliable GNSS (Global Navigation Satellite System) receivers for embedded systems, IoT devices, and robotics.
Powered by the u-blox NEO-6M chipset, this module delivers fast satellite acquisition, high accuracy, and stable GPS data even under challenging signal conditions.
It includes:
-
A high-gain ceramic patch antenna
-
On-board 3.3V LDO regulator
-
Backup battery (RTC) for hot-start capability
-
EEPROM for configuration storage
With a simple UART serial interface, it works seamlessly with 3.3V microcontrollers such as STM32 (Raayan Mini), ESP32, and 3.3V Arduino boards.
Perfect for:
-
GPS-based tracking systems
-
Robotics & autonomous navigation
-
Drones and UAVs
-
IoT location monitoring
-
Vehicle telemetry
-
Time synchronization applications
