## Description

A high-sensitivity GPS module built around the MTK3339 chipset, capable of tracking up to 22 satellites on 66 channels with 10 Hz position updates. At just 16 × 16 × 5 mm and under 6 grams, it packs an internal patch antenna, built-in datalogging, and ultra-low power consumption into a tiny footprint. The module features an external active antenna input that automatically detects and switches to an external antenna when connected. Built-in FLASH datalogging stores up to 16 hours of time, date, position, and altitude data at 15-second intervals — no microcontroller interaction needed after the initial start command. Key Features MTK3339 Chipset – 66-channel, 22-satellite tracking with −165 dBm sensitivity 10 Hz Update Rate – High-speed position updates for tracking applications Built-In Datalogging – Internal FLASH stores ~16 hours of GPS data (LOCUS) Internal Patch Antenna – With automatic switchover to external active antenna Ultra Low Power – 20 mA during navigation PPS Output – Pulse-per-second signal on GPS fix RTC Battery Compatible – Supports backup battery for hot starts Specifications Chipset – MTK3339 Channels – 66 (22 tracking) Sensitivity – −165 dBm (tracking) Update Rate – Up to 10 Hz Operating Voltage – 3.3V Current Draw – 20 mA (navigation) Dimensions – 16 × 16 × 5 mm Weight – ~6 g Note: This is the bare GPS module only — no breakout board or other components included. Soldering is required for integration. The module is available in the Adafruit Eagle Library as GPS_FGPMMOPA6H.
