This small, 2 W speaker is a compact way to add loud, high-fidelity sound (compared to typical units this size) that can bring your project to life. It includes four 1.0mm-diameter mounting holes. This is the highest-power speaker we carry.
This automotive-quality 0.15W speaker is a compact way to add sound to your project. The 100Ω impedance makes it easy to drive this straight from a microcontroller I/O pin.
This piezo sounder is an inexpensive way to add sound to your project. The wide operating voltage of 1 – 30 V and low current draw (5 mA at 9 V) make it easy to control this buzzer directly from a microcontroller I/O line.
Ready to add sound detection to your next project? This compact breakout board from SparkFun couples a small electret microphone with a 100x opamp, converting sound into amplified analog voltages that can be measured by a microcontroller’s analog-to-digital converter (ADC). The unit comes fully assembled as shown and works from 2.7 to 5.5 V.
Ready to add sound detection to your next project? This small breakout board from SparkFun couples a tiny microelectromechanical system (MEMS) microphone with a 67x gain external amplifying circuit, converting sound into analog voltage signals that can be measured by a microcontroller’s analog-to-digital converter (ADC). The unit comes fully assembled as shown and works from 1.5 to 3.3 V.
Make some noise with your next project! The MP3 Trigger board is built to make MP3 sound integration easy. The board has 18 external trigger pins that will directly trigger pre-selected MP3 tracks, and a full-duplex serial control port that provides remote triggering for up to 256 tracks and fast, real-time volume control. MP3s are played from a FAT16 formatted SDSC or FAT32 formatted SDHC micro-SD flash memory cards (required but not included). In addition, it achieves 192 Kbps stereo playback from a wide range of cards.
This is an evaluation board from SparkFun for the Silicon Laboratories Si4703 FM tuner chip. Beyond being a simple FM radio, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information. The Si4703 does filtering, carrier detection and captures data such as the station ID and song name.
