Hello.
It should be possible. Someone on our forums connected a similar GPS module to their Baby Orangutan, which is quite similar to the 3pi. I would start by looking at that. The LS20031 needs to be powered from a 3-4.2V source, so you will need a separate voltage regulator that lowers the voltage and supplies at least 100 mA. Also, the GPS serial connections are not 5-volt tolerant, so you will need a voltage divider to divide down the 3pi’s 5V serial.
