Installation
Installation of the SoundPAL is a simple. If you’re using a system that incorporates three-pin servo
headers (such as the BOE), just plug the SoundPAL into one of them. It has two three-conductor sockets
to choose from for this purpose, and you can insert either one in either direction, yielding four possible
orientations. The SoundPAL will adapt to whichever way you plug it in. Here’s a diagram showing the
SoundPAL’s pinout:
The photo below shows the SoundPAL plugged into a servo connector on the BOE Bot.
You will notice from the photo that the “sonic resonator” has been installed on the speaker. This is
provided both to increase the volume level of the SoundPAL and to give it a richer sound.

Important Note: The SoundPAL is designed to work from 5 volts only! Do not jumper your servo
headers to Vin or use any supply higher than 5 volts to operate the SoundPAL. Operation at lower
voltages down to about 3.3V is okay but will result in diminished output volume.
