Hello!
I successfully built my first wifydra tonight, however I ran into a problem with the GPS module. I was unable to get a GPS lock and the module appeared to be unpowered. The VIN pin was getting just 1.5v, not enough to run the module. Digging into it, I believe the PCB revision currently uploaded has an error. The EN pin on the ESP32-S3 is connected to VIN on the GPS module. According to the documentation this pin should only be pulled to ground if you want to disable the 3.3v regulator on the ESP32-S3 otherwise it remains high. I cut the trace that leads to this pin and put in another bodge wire from the VIN on the board. The GPS module LED now lights and I was able to successfully get a GPS lock.
