## Description

For those who want to integrate Adafruit's awesome Ultimate GPS module into their own projects, Adafruit now have the raw sub-module available. Don't be fooled by its small size, this is a very sensitive, high-quality GPS module with all the extras you could want and more at under 6 grams!

**As of August 2021, [the original "Ultimate GPS" module Adafruit used](https://core-electronics.com.au/ultimate-gps-module-66-channel-w-10-hz-updates-mtk3339-chipset.html) was discontinued by the vendor.** [Adafruit found and are using a nearly-identical version of the module - it's a little taller (4mm) but has the same functionality. ](https://core-electronics.com.au/attachments/localcontent/CDPA1616DDatasheetv_15226fcf12c.pdf)The commands for querying the antenna have changed slightly so existing projects may need to update their firmware.It's got everything you want and more:

- -165 dBm sensitivity, 10 Hz updates, 66 channels
- Ultra-low power usage: 20mA current draw while tracking
- 3.3V operation,
- RTC battery-compatible
- Built-in datalogging
- PPS output on fix
- Adafruit have received reports that it works up to ~32Km altitude (the GPS theoretically does not have a limit until 40Km)
- Internal patch antenna + connection for optional external active antenna
- Fix status output
- Ultra small size: only 16mm x 16mm x 6.4mm
 
The breakout is built around the MTK3333 chipset, a no-nonsense, high-quality GNSS module that can track up to 33 satellites on 99 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 ~29 mA during navigation.

Two features that really stand out about the MTK3333-based module are the external antenna functionality and the built-in data-logging capability. The module has a standard ceramic patch antenna that gives it -165 dBm sensitivity, but when you want to have a bigger antenna, you can snap on any 3V active GPS antenna via the uFL connector. The module will automatically detect the active antenna and switch over! [Most GPS antennas use SMA connectors so you may want to pick up one of Adafruit's uFL to SMA adapters.](https://core-electronics.com.au/sma-to-ufl-u-fl-ipx-ipex-rf-adapter-cable.html)

**This item is just the GPS module itself, no breakout board or other components included.** The module can be soldered by hand without too much difficulty, Adafruit have it in Adafruit's Eagle Library (GPS\_FGPMMOPA6H) to make it easy to use. If you're interested in getting started fast, check out Adafruit's **[Ultimate GPS breakout board](https://core-electronics.com.au/adafruit-ultimate-gps-with-usb-66-channel-w-10-hz-updates.html)** which comes all assembled and tested.

Adafruit have a nice fancy library for GPS usage for both Arduino and Python usage. [A full tutorial is also available, which has tons of information about the module, how to use the data logger, example code for both CircuitPython & Arduino, and more](https://learn.adafruit.com/adafruit-mini-gps-pa1010d-module).
