Adafruit Mini GPS PA1010D - UART and I2C - STEMMA QT

This miniature GPS breakout measures a mere 1" x 1" (~25mm x 25mm) yet contains a comprehensive GPS/GNSS solution with integrated I2C and UART interfaces. The built-in antenna ensures a seamless, plug-and-play experience.

Supporting GPS, GLONASS, GALILEO, and QZSS, this unit boasts a sensitivity of -165 dBm and can deliver up to 10 location updates per second, perfect for responsive tracking and logging applications. With 210 PRN channels, 99 search channels, and the capacity to track 33 channels simultaneously, it ensures precise navigation.

Its 5V-friendly design consumes only 30mA during operation. It features UART and I2C interfaces, allowing flexibility in connection preferences, and is breadboard-friendly with four mounting holes. The module includes PPS output with ±20ns jitter, a low-power standby mode, and a WAKE pin for efficient energy management.

Leveraging the robust MTK3333 chipset, this GPS breakout offers a dependable solution for compact, high-sensitivity applications. An internal patch antenna complements its small form factor, and optional CR1220 battery support provides real-time clock functionality. Integrated LEDs indicate power status and GPS fix quality.

Incorporating ultra-low dropout 3.3V regulation, this breakout is compatible with 3.3-5VDC inputs, with safe 5V inputs on both UART and I2C. A modern SparkFun Qwiic compatible JST SH connector enables solder-free connections, simplifying integration with favorite microcontrollers or Blinka-supported SBCs.

Each module comes assembled and tested, with a header for breadboarding and provisions for a CR1220 coin cell holder. Comprehensive tutorials and libraries for both Arduino and Python ensure ease of use, making this GPS breakout a superb choice for compact projects requiring accurate positioning data.
