GPS Logging Shield for Arduino
Overview
The 1272 is an assembled and tested GPS shield designed specifically for Arduino Uno, Leonardo, and earlier boards. It features a high-sensitivity GPS module with -165 dBm sensitivity, an integrated SD card interface for data logging, and a built-in RTC battery to maintain time synchronization. The board includes a prototyping area and status LEDs for power, pin 13, and satellite fix status.
Why Choose This Part
This shield combines GPS reception and SD card logging on a single board, reducing the wiring complexity of multi-module setups. Its high sensitivity and PPS output provide precise timing and positioning even in challenging environments, while the internal patch antenna offers a compact footprint with the option for external antenna expansion.
Applications
Getting Started
Plug the shield into a compatible Arduino Uno or Leonardo board and ensure the RTC battery is seated. Use the standard TinyGPS++ library for NMEA parsing and the SD library for file operations. Ensure the device has a clear view of the sky for the initial satellite fix, which is indicated by the onboard Fix LED.
