hiBCTR NEO-7M 3.3V-5V STM32, C51, 51 GPS Module with SMA Antenna, TTL UART High-Precision GPS Tracker for Arduino, MCU

High-Precision GPS Tracking: u-blox NEO-7M module with 56 acquisition/22 tracking channels ensures reliable positioning under dense foliage or urban canyons. Dual Antenna Flexibility: Switch between onboard ceramic antenna (20dB gain) and external active antenna via SMA connector for optimal signal strength. Development-Friendly Integration: Voltage Support: 3.3V-5V DC input with reverse polarity protection Communication: 9600bps UART (TXD/RXD) compatible with Arduino Uno, STM32F4, and 8051-based systems Data Output: NMEA 0183 protocol + proprietary u-blox UBX binary Enhanced Features: Battery Backup: 12mAh coin cell socket for hot-start <1s (retains ephemeris data) 1PPS Output: 30ns synchronized pulse for time-critical applications Software Tools: Configure baud rate/fix rate via u-center (Windows) or embedded AT commands; includes Arduino library for parsing latitude/longitude. Applications: Drone/AGV navigation systems Fleet management OBD-II trackers Weather balloon telemetry Package Contents: 1 NEO-7M GPS module with pre-soldered headers + antenna, datasheet, and sample code link. Compliance & Safety: RoHS-compliant design with ESD protection; ensure USB-TTL converter supports 3.3V/5V logic to avoid damage. Note: For optimal performance, avoid obstructing antenna placement and ensure clear sky visibility during initial satellite acquisition (cold start <35s).
