Getting the position


Now it's time to take a look at the GPS receiver. The GPS we will be using is based on the MTK3339 chipset, which is very easy to use but still very powerful. Adafruit manufactures the board shown in Figure 5.1, and this module was built with wearables in mind. This GPS can track up to 22 satellites and has very low power consumptions, which makes it ideal for battery-powered projects. The GPS is incredibly easy to read, you just need to connect over the serial port and you are good to go. In Figure 5.3, you will find the necessary connections that need to be made. I recommend connecting everything using alligator clips while you are trying out the GPS receiver:

Figure 5.3: Connecting the GPS to the FLORA board

Don't forget to connect the serial pins in the right order. The TX pin of the GPS needs to connect to the RX pin on the FLORA board and vice versa, since we want to transmit from the transmitting pin to the receiving pin. The GPS module will receive the position...
