NEO-7M GPS Module with SMA Antenna

The NEO-7M GPS module is highly compatible with a wide range of microcontrollers, including Arduino UNO and STM32-based boards. It communicates via a standard TTL serial interface (TXD/RXD) and outputs NMEA-0183 protocol data, making integration straightforward for most embedded systems requiring precise location information for navigation.

This module operates reliably across a wide voltage range of 3.3V to 5V, ensuring flexibility for various embedded platforms. This broad compatibility allows it to be directly powered by both 3.3V and 5V systems without requiring external voltage regulators, simplifying wiring and integration into diverse drone and robotics projects.

The NEO-7M module features a built-in ceramic antenna for convenient, baseline satellite reception, even without external components. Additionally, it includes a welded SMA connector, allowing users to attach a high-gain external antenna. This dual antenna setup provides superior signal reception and improved accuracy, especially in challenging environments.

Yes, the NEO-7M GPS module is equipped with built-in FLASH memory. This crucial feature enables it to store user-configured settings, such as baud rate or output frequency, ensuring that these parameters persist even when the module is powered off. This eliminates the need for re-configuration upon every power cycle.

The PPS (Pulse-Per-Second) output on the NEO-7M module provides a highly accurate 1 Hz timing signal, with the rising edge precisely marking the start of each second. This feature is critical for applications requiring precise time synchronization, such as data logging, timestamping sensor readings, or coordinating multiple systems within autonomous platforms.
