Any significant differences between the Pnautic AP and the Pypilot.org AP?

[carl_dzinh]

I need an AP for a passage soon (New Orleans to Key West) and I'm assuming the store will be down for the foreseeable future.  Just wondering if the unit sold at Pcnautic ( https://pcnautic.com/en/product/pcnautic-autopilot ) is basically the same as the one sold in the pypilot.org store, in terms of functionality, etc.  Pardon my ignorance.  I'm new to sailing and this my first boat, and although I'm a web developer and fairly tech savvy I posses very little knowledge about electronics.  

I have wheel steering and my boat is ~22,000lbs.  I have a used CPT autopilot motor that I plan on using and still need some other components from the CPT system minus the "brain" they use.
