Port Array Module

Version 1, released November 2017

Version 2, released September 2025

The Port Array Module interfaces additional behavior ports to a Bpod State Machine.

Up to 5 port array modules may be used with a single state machine, for experiments requiring large numbers of behavior ports.

The Port Array Module is compatible with state machine r0.7+

Firmware for the Port Array Module is available here.
