The Adafruit Ultimate GPS Breakout v3 board is based on the MTK3339 chipset and supports position updates up to 10 times per second. It has a reception sensitivity of -165 dBm, a built-in patch antenna, and a u.FL connector for a 3 V active external antenna, which it detects automatically. The built-in logging feature saves the time, date, longitude, latitude, and altitude to FLASH memory every 15 seconds, but only when a position fix is available.
The board operates on a 3.3–5 V DC supply, has inputs compatible with 5 V logic levels, and draws 20 mA during navigation. It features an ENABLE pin for shutdown via a microcontroller or switch, a PPS output when a position fix is available, and a status LED. FLASH memory stores approximately 16 hours of logs, while the CR1220 battery holder keeps the real-time clock running and supports hot starts.
