Hello Renato!
Do you have a PCB or are you connecting the parts with separate wires? Check out my post, are you building the same setup? https://discourse.agopengps.com/t/basic-panda/11082?u=16759
If you use ethernet to connect the Tennsy 4.1 to the tablet/PC you can do what I did and use tag/5.6.33 SupportFiles.zip succesfully the other day. In the SupportFile folder \TeensyModules\Firmware\Autosteer_gps_teensy_v5_5 you find Autosteer_gps_teensy_v5_5.ino. Upload this to the Teensy.
1 usb to the Teensy is enough to power both the Tennsy and the F9P if you have the same connection setup as in the post I linked, but you can use both.
Have you already configured the F9P?
