Black Box Toolkit USB Response Pad

Simply plug in to a USB port on your PC/Mac/Linux system and our response box will appear as a second keyboard. Press a button and a standard keystroke will be sent to your experiment. No need for drivers, no need to recode! Works out of the box with E-Prime, SuperLab, Presentation, Inquisit, PsychoPy or any other software that can accept standard keyboard responses.


Black Box Toolkit USB Response Pad with Voice Key

All the great features of our standard USB Response Pad but with an integrated voice key. If your participants make a vocal response this also produces a standard key press and TTL event mark/trigger! Simple to use and simple to setup with tunable vocal activation threshold. It's your choice whether to use it as a standard response pad or use it as a voice key. Supplied complete with headset.


API & SDK guide

Printed documentation detailing our software API which allows you to control the mBBTK from your own applications and decode timing data. The mBBTK is controlled via a virtual serial COM port over a USB or Bluetooth connection using simple four letter commands.


BBTK digital microphone

Up to two can be used simultaneously for monitoring for auditory stimulus (adjustable trigger threshold).


48-way TTL breakout board

Allows for 24x TTL/TTL trigger inputs and 24x TTL event marking outputs/TTL triggers in addition to other input sensors such as opto-detectors, mics and response pads etc. Also includes 24x grounds.


Opto-detector sensor and cable

Up to four opto-detector sensors can be used with the mBBTK v2 to monitor for the appearance of a visual stimulus.
