Well hello there, everyone, and welcome back to another fantastic Friday Product Post here at SparkFun Electronics. We have a pretty fun filled Friday in store for you with three aptly named audio boards for your choosing: a 1.5W stereo/mono amplifier with a built in potentiometer and two easy-to-use audio playback board. On top of these three new boards, we are also releasing a new 12 button keypad for whatever project you may need it for! Without further delay let’s take a closer look at all the new products we have for you this week!
With great power comes great responsibility… but that’s no fun! Just prank your friends with Smashmouth!
You won’t need a series four de-atomizer with our rendition of the Noisy Cricket, just wire it up and crank up your tunes! The Noisy Cricket Stereo Amplifier, uses the LM4853 Boomer® IC which can be configured to output up to 1.5W of power in mono operation (4Ω load) or 300mW per channel in stereo operation (8Ω load). The amplifier comes with a dual-ganged pot with a built in switch to control power and adjust both left and right channel gain.

The SparkFun Little Soundie is a fun and easy-to-use audio playback device breaking out the VS1000D audio codec IC allowing this little board the ability to decode OGG Vorbis and WAV type files. The Little Soundie makes adding sound effects to your project, prop, or costume easily with the built-in USB mass storage for your audio files and simple methods of triggering audio playback. Beyond playing back your chosen audio files, the Little Soundie is remarkably easy to set up, with just four simple steps: connect to your computer using a micro-USB cable, press the power/play button, format the disk when prompted, then just rag and drop your .ogg or .wav files!

The SparkFun Papa Soundie is the upgraded version of the Little Soundie with similar areas that allow you, the user, to interact with the board but with more customizable options. It still supports OGG Vorbis and WAV type files but with an SD card for sound storage and a built-in ATmega328P programmed with Arduino you’ll be adding custom sound effects to your project with less hardware and in a familiar programming environment.

This is a basic 12 button keypad that has been designed for easy user input and functionality. The buttons are set up in a matrix format. This allows a microcontroller to ‘scan’ the 7 output pins to see which of the 12 buttons is being pressed.
Each of the keypad’s 12 buttons has been labeled 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, *, and # and has been formatted to into the same layout as a telephone keypad with each keypress resistance ranging between 10 and 150 Ohms.
