The Adafruit Mini GPS PA1010D is a compact 25×25 mm GPS/GNSS breakout with a built-in patch antenna, dual UART and I2C interfaces, and STEMMA QT connectors for solderless plug-and-play use. Powered by the MTK3333 chipset, it supports GPS, GLONASS, Galileo, and QZSS satellite systems with up to 10 Hz position updates.

With −165 dBm tracking sensitivity, 30 mA navigation current, and 5V-friendly design, this module is ideal for compact projects where space and power are at a premium. Unlike the Ultimate GPS modules, this one is designed to be as small as possible — there's no external antenna connector.
