Compatibility of RAK19010 baseboard?

[madeofstown]

I'm in the process of creating a portable solar rechargeable power station for camping and I decided that using a Meshtastic radio for a theft tracker would be a great option. I decided on RAK wisblock because of how easy it will be to add GPS module, temp/humidity sensor, as well as module to monitor the voltage of my 12v lipo. Then I realized that if I picked the baseboard with the modular power supply I could easily have it running on 12v too!

Now I got everything built up but here's my problem, the firmware cannot seem to find my GPS module. I've tried it on every slot where it would fit, (even in slot b with it hanging off the side of the baseboard) and firmware just runs through trying each baud rate and eventually gives up. I've since tested the GPS module on a different set-up that uses the 19007 baseboard and it is found without issues.

Is there something different with the GPIO wiring on the 19010 that would cause this incompatibility?

I'm sure somebody here knows what's going on with this... After looking through documentation from RAKWireless I cannot see anything different between the 19010 and the 19007 except for the modular power connector.
