Welcome to the gps-ada wiki!

Quick list of the material needed:

• A leonardo; if you use a uno or another Arduino, there are a few things to change, it could probably work, but you’re on your own ;-) The real interest of the Leonardo here is that you can use the Serial1 HW serial to talk to the GPS so I took software serial out altogether which saves some memory space (and it’s tight) and some headaches also…​

• An ultimate GPS shield from adafruit: you can also use the ultimate GPS module (not the whole shield) also but then you have to get an SD reader also. Important note: you have to modify the shield (very easy) to be able to use the hardware serial1 of the leonardo to communicate with the GPS. First put the serial switch of the shield on software serial (no its no mistake) and then solder two wires from the tx and rx on the shield to pins 0 and 1 on the shield also (I will put a picture later on to show how). Make sure the GPS RX goes to pin 1 as it must be connected to TX of the arduino and the GPS' TX goes to pin 0, which is Arduino’s RX). One more thing: the pins 7 and 8 on the shield are now unusable, but if you want to be able to use the pins 7 and 8 of the Arduino, make sure you solder the headers on the GPS shield without these pins (also to be shown on the pictures).

• An LCD (16x2) controllable via the arduino library.

• A few wires, resistors and a rotary encoder with a button: you can turn it and also push it to navigate the menus.
