The GPS NEO‑7M Satellite Positioning Module is a high-precision GNSS receiver board designed for makers, drone builders and embedded platforms such as Arduino UNO or STM32 based boards. It comes equipped with both an on-board ceramic antenna and a welded SMA connector for attaching an external antenna to boost signal reception.
The module supports standard NMEA output, features built-in FLASH memory to retain settings after power-off and offers a simple micro USB interface for debugging alongside TTL serial connection for MCU integration. It accepts a wide supply range (3.3-5 V), making it ideal for both 5 V and 3.3 V systems. With its compact size and strong satellite lock capability, this module is perfect for outdoor positioning, drones, robotics navigation or GPS timestamping applications.
Features:
- On-board ceramic antenna provides reliable satellite lock even without using an external antenna.
- Welded SMA connector allows connection of an external high-gain antenna for stronger GPS reception.
- Supports standard NMEA protocol output, making it easy to interface with Arduino, STM32, and other MCUs.
- Built-in FLASH memory stores configuration settings and retains them even after power is removed.
- Micro USB interface enables quick debugging and direct PC connectivity.
- TTL serial interface (TXD/RXD) ensures simple and direct communication with microcontrollers.
- PPS (Pulse-Per-Second) output provides accurate timing signals for precision-based applications.
- Wide operating voltage range (3.3 V – 5 V) ensures compatibility across various development platforms.
