So what does the Raspberry Pi 2 GPS kit include?

MicroStack protoyping board to plug in the GPS add-on.

Raspberry Pi 2 with a microSD card pre-loaded with NOOBS with various OS options, but Raspbian is best for utilising the add-on boards.

Raspberry PiFace control and display board adds an LCD display along with infra-red sensor and buttons.

Pi Shim allows you to breakout the GPIO, when it is not being used by an add-on board.

The interesting part is the Microstack GPS add-on board and the Microstack baseboard provides I2C and SPI pins for connecting the board to the Raspberry Pi module.

What about the GPS antenna? The GPS add-on board has an active high-gain antenna. But you can add an antenna using the add-on board’s uFL connector. However, to connect an active antenna, it requires this add-on cable to adjust it to an SMA plug.

The power supply is a standard 5V 2A Pi power supply.
