Adafruit Mini GPS PA1010D - UART and I2C - STEMMA QT

This miniature GPS breakout is only 25mm x 25mm but houses a complete GPS/GNSS solution with both I2C and UART interfaces. There's even an antenna on top, so it's plug and play!

Specifications

• Support for GPS, GLONASS, GALILEO, QZSS
• -165 dBm sensitivity, up to 10 Hz updates
• Up to 210 PRN channels with 99 search channels and 33 simultaneous tracking channels
• 5V friendly design and only 30mA current draw
• Breadboard-able, with 4 mounting holes
• UART and I2C interfaces, pick whichever you like most!
• RTC battery-compatible
• PPS output on fix ±20ns jitter
• Internal patch antenna
• Low-power and standby mode with WAKE pin

The breakout is built around the MTK3333 chipset, a reliable, high-quality GPS module that can handle up to 33 simultaneous tracking channels, has an excellent high-sensitivity receiver (-165 dBm tracking!), and a built-in antenna. It can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low, only 30 mA during navigation.

Adafruit added an ultra-low dropout 3.3V regulator so you can power it with 3.3-5VDC in, 5V level safe inputs on UART and I2C, a footprint for optional CR1220 coin cell to keep the RTC running and allow warm starts, a green power LED and a tiny red PPS LED. The LED blinks at about 1Hz when a fix is found and is off when no fix.

Comes with one fully assembled and by adafruit tested module, a header you can solder to it for breadboarding, and a CR1220 coin cell holder.

Note

This module does not have the ability to connect an external antenna, it's designed to be as small as possible for compact projects.
