Try “” they will probably have something.

Depending on how handy you are, there are plenty of circuits out there for ‘do it yourself’ amplifiers …


Good Luck

Subject: [Gumstix-users] Audio In/Audio Out with Palo35




I noticed that on the Audio How-To page at, it says that an amplifier is needed for Expansion Boards without a stereo headseat jack in order for a microphone to be added.  


Could anyone point me in the right direction as to which amplifier I should buy?  I am using a Palo35 Expansion Board.
