Adafruit has this week announced the arrival of the MiniGPS PA1010D a miniature GPS breakout board priced at just under $30. Measuring just 25 mm x 25 mm the miniature GPS breakout board houses a complete GPS/GNSS solution with both I2C and UART interfaces.
“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.
Best of all, we added all the extra goodies you could ever want: a 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.”
