Hey Björn,

Unfortunately, the deign of EEG-SMT does not allow hardware expansion. EEG-SMT is targeted at people with less electronics knowledge and meant to be used without hardware modifications. You can use multiple EEG-SMT units however (this is described in the user's manual - you can easily reprogram the FTDI chip inside so that each unit has unique ID). The biggest challenge of using multiple EEG-SMTs would be the software - I couldn't find a piece of visualization software that can use two input devices.

The products that allow hardware expansion are EEG-ANALOG-ASM and EEG-DIGITAL-ASM, that follow the suggested OpenEEG hardware design almost blindly. There are other difficulties there though and electronics experience is required.

Best regards,
