2 Description

The BOS1901-KIT is a Development Kit to help

users who want to get familiarized with the

BOS1901 Piezo Haptic Driver IC.

The USB powered kit appears as an USB Audio

device for the computer, which allows the rapid

generation of waveforms using existing audio

software like Audacity® for haptic prototyping.

Each breakable miniature PCB gives access to all

signals allowing the user to experiment with the

BOS1901 using a development platform of his/her

choice.

Standard commercial piezo actuators are provided

as a starting point to begin experiencing with

haptic feedback.

Page 10 BOS1901-KIT User Guide pressure triggers a single light click, medium pressure triggers a stronger click, and a high pressure triggers a longer feedback. SW5 sets the frequency of the feedback response when the actuator is pressed and released. SW6 sets the amplitude level of the feedback response. Setting SW6 to ON will provide a stronger response than setting it to OFF.
