GPS logger shield with Uno and another shield

GPS/GNSS Development Boards

Hello,

I am working on a project with the GPS logger shield, GPS-13750, an Arduino Uno, and a Freetronics LCD keypad shield. The LCD uses D3-D9 and A0. So it seems that the logger shield is hardwired to D8/D9 for GPS RX/TX. Would I be able to reroute these to different Arudino pins? What pins should I use? I wanted to make sure of this before I started cutting traces.

Thanks,

Scott

As per the GPS Logger Shield hookup guide: “If you need to move the software serial port pins, they can be custom-routed to any other pin by cutting the solder jumpers between pins GPS-RX and D8 and/or GPS-TX and D9.” (https://learn.sparkfun.com/tutorials/gp … e-overview). If you have a HW Serial compatible microcontroller then I would use the on board switch to use that instead if possible.
