Hardware
It's a Pi Zero W with a waveshare e-paper screen. See Pwnagotchi
If you want to run Bjorn on different Pi's there is https://github.com/HackCocaine/BjornCocaine - it also extends functionality but I don't know exactly how.
General Setup
See Pi_Zero_W
Setting up Bjorn
View https://github.com/infinition/Bjorn
NB the orchestrator may get stuck in awakening mode and not start WiFi if default locale is not set to en_GB.UTF-8 https://github.com/infinition/Bjorn/issues/40 and https://github.com/infinition/Bjorn/issues/112. You can see your locale by using the locale -a command and edit it in /etc/default/locale
USB Networking
This guide explains how to configure USB networking (usb0) on a Raspberry Pi Zero W using NetworkManager, so you can stay connected via SSH or a web UI even when switching WiFi networks.
I had the problem where the otg would stop working if I switched wifi connections on Windows.
This as I said let's you stay connected to Bjorn if you use http://bjorn.local:8000/ or if you ssh into bjorn with ssh bjorn@bjorn.local
https://github.com/iam-jorn/Bjorn-cyberviking-otg-fix
This is an issue with fixes for USB connectivity
https://github.com/infinition/Bjorn/issues/68
Using Bjorn
Connect to WebUI over Wifi using http://bjorn:8000/
Web UI Explanation
NB if you change settings you have to press the Save button in the menu above :)
The buttons in the UI show the status, they are not necessarily instructions :)
You can see what it is doing by selecting the Playground (top left) and clicking on the red "OFF" button.
You can add wordlists (usernames and passwords) in ~bjorn/Bjorn/data/input/dictionary/
SecLists is a good source for lists (nb the 153MB rockyou text has issues, see below). https://github.com/danielmiessler/SecLists/tree/master/Passwords/Common-Credentials is a good start for passwords and https://github.com/danielmiessler/SecLists/blob/master/Usernames/Honeypot-Captures/multiplesources-users-fabian-fingerle.de.txt for usernames
Addon Modules
https://github.com/LOCOSP/BjornWpaSecHarvester - download and process Wi-Fi network data caputered by Pwnagotchi, processed with wpa-sec, and inject the networks into your Bjorn system. Additionally, it integrates with Discord to optionally send the collected networks to your server
Nice 3d Printable cases

Troubleshooting
Logs in ~bjorn/Bjorn/data/logs
https://github.com/infinition/Bjorn/blob/main/TROUBLESHOOTING.md
https://github.com/infinition/Bjorn/issues/64 - soft limit on Pi Zero, so Bjorn stuck on idle waiting due to large password file rockyou.txt
https://github.com/infinition/Bjorn/issues/44 - you may have problems switching from one WiFi network to another one using the web ui.
