HACKING THE VPN1513 GPS Smart Module with External Antenna
![pilot0315](https://forums.parallax.com/uploads/userpics/394/n1NU2QCNW74FC.jpg)
This module has a prop chip attached. The data sheet is not explicit but I got info from them regarding hacking it. They talk about hacking it in the sheet a bit.
Power the board via the vdd and gnd either by the existing pins or as seen in the data sheet. Prop plug works well. Pins 26 and 27 are directly from the gps chip.
Wipe the EEprom and write your own code and upload. Or tap into pins 26 and 27 direct feed from gps available. I did this both ways works well.
Gonna probably use the board as both in my present project. Robotic GEM telescope mount.

I have not had time to finish up the hack but hope to get it done by Sunday.
I will post the results. BTW I found that the enable pin takes the power supply to gnd. It did not jump right out at me in the schematic.
