This incredibly small stereo amplifier is surprisingly powerful - able to deliver 2 x 3.7W channels into 3 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, its incredibly efficient (over 90% efficient when driving an 8O speaker at over a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. This board is a welcome upgrade to basic "LM386" amps!
The inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the R- and L- to ground. The outputs are "Bridge Tied" - that means they connect directly to the outputs, no connection to ground. The output is a 360KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it'should drive the speakers directly.
Comes with a fully assembled and tested breakout board with 1.0uF input capacitors. We also include header to plug it into a breadboard, 3.5mm screw-terminal blocks so you can easily attach/detach your speakers, and a 2x4 header + jumper to change the amplifier gain on the fly. You will be ready to rock in 15 minutes! Speakers are not included, use any 3ohm or greater impedance speakers.

This breakout board is the ultimate companion for the VLSI VS1053B DSP codec chip. The VS1053 can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It can also be used to record audio in both PCM (WAV) and compressed Ogg Vorbis. You can do all sorts of stuff with the audio as well such as adjusting...
This is the Teensy Audio board add-on for the Teensy 3.0 and 3.1 development boards. This audio board provides you with an easy-to-use tool to add high quality 16 bit, 44.1 kHz sample rate audio to your Teensy project. With the audio library provided in the Documents section below you will be able to use both the input and output simultaneously in order...
In secure embedded systems, you often need to authenticate messages or connected devices but many microcontrollers aren\'t set up for the necessary cryptography. That\'s where the Atmel ATSHA204 comes in.
Immer die beste Verbindung: Schließen Sie Ihr Smartphone oder MP3-Gerät an Ihr Autoradio per AUX-Buchse oder an Ihre Heim-Hi-Fi-Anlage. Das Stereo Anschlusskabel von LogiLink macht es möglich. Länge: 1 m.
The RPI-1031 tilt sensor is capable of sensing a change in orientation in four different directions: forward, back, left or right. This breakout board makes it easier to incorporate the RPI-1031 in your next project by breaking the necessary pins out to standard 0.1" spaced headers. This board will work at either 3.3 or 5V.

A Feather board without ambition is a Feather board without FeatherWings! This is the Latching Mini Relay FeatherWing . It gives you power to control, and control over power. Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any Feather board.
