Audio boards, amplifiers, speakers and microphones for Raspberry Pi, Pico and other microcontrollers, whether you're building a music player, adding sound effects to a project or recording audio.
Audio for Raspberry Pi and Pico
For high-quality audio output from a Raspberry Pi or microcontroller, an I2S DAC converts digital audio into a clean analogue signal. This is especially useful with Raspberry Pi 5, which has no built-in headphone output.
Amplifiers and speakers
A DAC or line-out signal needs an amplifier before it can drive a passive speaker. The PAM8302 is a compact 2.5W mono amplifier, while the 3.7W stereo amplifier can drive a pair of speakers. For larger projects, the Yukon Audio Amp Module provides substantially more power.
If you just want to make some noise with minimal fuss, the STEMMA Speaker combines an amplifier and speaker on a single board. We also stock a range of separate speakers in different sizes and power ratings - just make sure the impedance and wattage are suitable for your amplifier.
Microphones and sound effects
For recording and sound detection, the MAX9814 electret microphone amplifier provides an analogue microphone signal with automatic gain control, while Pirate Audio Dual Mic adds a pair of digital microphones to a Raspberry Pi.
If you want sound without running a full computer, the Audio FX Sound Board can play WAV and OGG files when its trigger pins are activated - handy for props, models and interactive exhibits. Tiny FX combines sound and lighting control for miniature scenes and dioramas, while Tiny FX W adds wireless connectivity.
