Also, take a look at the [Auto-configuration](https://github.com/1oginov/UBX-GPS-Library/blob/master/Configuration/Auto-configuration-Mega/Auto-configuration-Mega.ino) sketch for the Arduino Mega boards to configure your GPS module automatically to get NAV-PVT messages with 100 ms frequency and 115200 baudrate.

+### Auto-configuration

+After wiring you can upload the [Auto-configuration](https://github.com/1oginov/UBX-GPS-Library/blob/master/Configuration/Auto-configuration-Mega/Auto-configuration-Mega.ino) sketch for the Arduino Mega boards to configure your GPS module automatically.

+At the moment it configures the receiver to get NAV-PVT messages with 100 ms frequency and 115200 baudrate, but you can change it according your needs.

+You are not required to follow next steps and [use u-center](#step-3-meet-u-center) after that, you can pass to the [Checks](#step-9-checks) step instead.

 ### Step 2. Serial bridge
 
 Let's make a bridge between GPS module and computer: upload `Serial-Bridge-Uno.ino` or `Serial-Bridge-Mega.ino` sketch on the board, it allows us to communicate with GPS module directly from computer. Open _Serial Monitor_, and if your GPS module is new or have default settings you will see something like on the picture below. If everything is OK, GPS will send some data.
