Hello and welcome, everyone!This week, we have two new versions of some of our favorite audio boards with the Teensy Audio Adaptor Board and the EasyVR 3 Plus Shield for Arduino. Following those up we have a new HC-SR04 Ultrasonic Distance Sensor, and our very own NOOBS card - a more economical solution for setting up your favorite Raspberry Pi board.

Teeny but LOUD!

Teensy 3 Audio Shield (Rev C)

1 Retired

This is the Teensy Audio Adapter Board that can be added to a Teensy 3.0, 3.1, 3.2, 3.5 or 3.6 for your next audio project. The shield provides you with an easy-to-use tool to add high quality 16-bit, 44.1 kHz sample rate audio to your Teensy. With the audio library provided in the Documents tab, you will be able to use both the input and output simultaneously in order to make a variety of great audio projects, incorporate synth waveforms and effects, and mix multiple sound streams and CD-quality audio to your headphones or different line outs!

Easy peasy, lemon squeezy!

EasyVR 3 Plus Shield for Arduino

EasyVR 3 Plus Shield for Arduino


Do you make time to talk to your Arduino? Maybe you should! The EasyVR 3 Plus Shield is a voice recognition shield for Arduino boards integrating an EasyVR module. This kit includes the EasyVR 3 Plus Module, the Arduino Shield Adapter, microphone and headers. With all of these parts, everything has been provided to you to get up and running in a short amount of time with minimal soldering!

Ultrasonic Distance Sensor - 5V (HC-SR04)

Ultrasonic Distance Sensor - 5V (HC-SR04)


The HC-SR04 ultrasonic distance sensor is an economical sensor that provides 2 cm to 400 cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3 mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.

This version of the sensor has additional control circuitry that can prevent inconsistent "bouncy" data depending on the application.

SparkFun Noobs Card for Raspberry Pi (16GB)


This is a class 10, 16 GB, micro SDHC card that has been pre-installed with the NOOBS operating system for the Raspberry Pi, produced here at SparkFun. This SD card is perfect for a Raspberry Pi first-timer or beginner, while still providing convenience for anyone with more experience. This little card allows you to start using your Raspberry Pi straight out of the box without worrying about imaging it on your own.

That's it for this week! As always, we can't wait to see what you make! Shoot us a tweet @sparkfun, or let us know on Instagram or Facebook. We’d love to see what projects you’ve made!

    For quite a few hours (about 2 days, in fact) I was getting the "we're putting ourselves back together" thing instead of the usual SparkFun web site. The thought occurred to me that if someone were "desparate" to order something, they could (likely) call up and place an order by telephone -- IM[NS]HO, it would be wise to modify the "back together" page to include said telephone... (Fortunately, I didn't happen to need to order anything at the moment, and could probably dig up the number from other resources.)

    Is this a typo? "This version of the sensor has additional control circuitry that can provide inconsistent "bouncy" data depending on the application."

    If its not a typo, then I would prefer you keep that additional circuitry and I'll go about my day without inconsistent bouncy data. ;-)
