You guys were very gracious and sent me a replacement RobotHat v5 kit (RobotHat v5, + 12 compatible servos & new battery) so I will be able to use the PiDog with my RPi5. Is there a newer set of instructions I can download for this updated PiDog v2?
Thanks again for sending me this newer kit I *really* appreciate it! 
The PiDog V2 uses the same online tutorial manual as the PiDog V1:
https://docs.sunfounder.com/projects/pidog/en/latest/.
However, there are some differences which are noted in our tutorial.
For the PiDog V2, you no longer need to run code to reset the servos. You can follow the printed assembly guide for the PiDog V2 to install it. https://drive.google.com/file/d/1FYEeTHCi9loLBctQiD8JaQiE3Dves2vB/view?usp=drive_link
Hi, could you provide a link to the original (v1) assembly guide, as you have for the V2? The PDF is so much easier to follow.
Thanks, Steve.
