Enhance a simple rubber hand puppet with MONSTER M4SK eyes and voice changer!
By snapping the MONSTER M4SK in half (safely!) and joining the halves back together with the 9-pin JST SH cable, you can place extra awesome eyes on a rubber hand puppet, such as the dinosaur shown here. And, the PDM microphone and audio output allow us to run voice changer code for extra puppeteering fun!
