These are two raspberry pi zero w projects that seem the same but are very different.
The pwnagotchi is an AI powered deauther that tries to get the handshake between a user and the wifi they are connected to. This helps attackers to get the handshake for multiple wifis without really doing any work.
Bjorn on the other hand is more like a personal network engineer that you give access to your own network and he will try to break in and show you all the ports your internal network has.
Both of the projects could work hand in hand if an attacker were to get the credentials to log into a wifi network from the pwnagotchi then use Bjorn to scan the network for any vulnerabilities. The way I see it, having a Bjorn is great for defenders to have an automated set of eyes testing your network. As for the pwnagotchi is more for an attacker.
These projects can be found at the following
