Hypno Hardware Versions
Hypno is based on the Raspberry Pi mini-computer. The Hypno works with most Pis currently in production to allow for greatest supply flexibility and device
The different Pis have a few hardware differences and wether you want to use your Hypno in the Eurorack will dictate which Pi is best for your needs, the Pi is
user switchable and source-able by the user (try rpilocator.com) so acquiring a single setup does not prevent you from converting your Hypno to one that is
