Ublox NEO-7m GPS Module HW-542B

Description

Ublox NEO-7m GPS Module HW-542 The Ublox HW-542 NEO-7M GPS Module is a high-performance GPS receiver module engineered for precise positioning and navigation applications. Built around the Ublox NEO-7M chip, this module delivers exceptional sensitivity and accuracy, making it an excellent choice for drones, robotics, vehicle tracking systems, and other smart electronics projects. It features an external SMA connector for attaching a GPS antenna, ensuring robust signal reception in challenging environments. The module communicates primarily through a UART serial interface and supports both 3.3V and 5V power supplies, enabling seamless integration with microcontrollers such as Arduino and Raspberry Pi. Features: GNSS Support Supports GPS, GLONASS, QZSS, and SBAS (WAAS, EGNOS, MSAS) for enhanced positioning accuracy. Position Update Rate Up to 10 Hz for real-time tracking. Time to First Fix Cold start: 30 seconds; Hot start: 1 second. Position Accuracy 2.5 meters (autonomous), 2.0 meters (with SBAS). Sensitivity Tracking and navigation: -161 dBm; Cold start: -147 dBm. Interfaces UART. Power Supply Compatible with 3.3V to 5V systems, likely via an onboard voltage regulator. Backup Battery Rechargeable battery for faster startups and maintaining settings. EEPROM Stores configuration settings for persistent operation. Antenna SMA connector for optimal signal strength. Operating Temperature -40°C to 85°C, suitable for diverse environments. Timing Output Pulse Per Second (PPS) signal for precise time synchronization.
