How do I get one?
~We are currently planning a small batch production run, stay tuned.~ No we are not, sorry
You don't want to wait? You can of course run a small batch on your own! Please have a look into the production folder, a batch size of just 5 (and up to 30) boards is supported by JLC.
Installation & Configuration
After downloading and flashing the image, OtterCastAMP can either be configured via the config.ini file or via the web-interface.
