CQRobot Speaker 3 Watt 4 Ohm Compatible with Arduino Motherboard, 2.54mm Dupo...

For such small speakers they sound great! I used a 15 watt Bluetooth amp for a small project and they were perfect and fit in a small space with mounting tabs.

Both units worked fine and are as represented. Using with Arduino (or clone) Uno / Nano and a 3 watt amplifier it sounds great. Not tinny or tiny sound. Deep notes sound good. No problem recommending, assuming the size fits your project.

For $8 (and two speakers) these aren't half bad, just don't expect to be getting god-tier quality out of them, and just be aware of how much you're spending for these two speakers. If you understand that, then these speakers will give you no problems. They're super simple to use, just hook them up to an amp and you're good to go.

The "Why" I needed a set of compact, low-profile speakers for some custom ESP32 microcontroller builds. Space is always at a premium in these small electronics enclosures, so I wanted something self-contained that wouldn't require a massive footprint or complex wiring. Performance For their tiny $28 \times 31\text{mm}$ size, these little 3-watt speakers are highly impressive. The JST-PH 2.0mm connector cable made hooking them up to the development boards completely plug-and-play—no tedious soldering required. The sound quality is clear, stable, and surprisingly crisp for a micro driver, handling basic audio alerts and tones without any distortion or weird buzzing. Their small form factor makes them exceptionally easy to tuck away into tight project cases. Pros & Cons Pros Compact Footprint: Tiny form factor fits easily into tight enclosures. No Soldering Needed: Pre-installed JST-PH 2.0mm connector cable makes setup instant. Solid Volume: Impressively loud and clear audio output for a 3W micro speaker. Sturdy Enclosure: The full-range cavity design keeps everything self-contained. Cons Wiring Clearance: Depending on your housing design, the wire placement might require a little extra relief inside the case. Final Verdict Rating: 5 / 5 Stars Who is this for? This pair is a perfect match for makers, tinkerers, and electronics hobbyists building custom ESP32, Arduino, or Raspberry Pi projects that need reliable, clear audio feedback without the bulk.

Worked as described

I evaluated this 2-pack of mini speakers for use in various electronics projects. I do not require hi-fidelity sound, but I do need something that is clear and stable, and these speakers delivered. They worked fine for me at all power levels using a tone generation program I programmed the Arduino to produce. I was able to vary the voltage and test at higher power (close to 3 watts) and also low power. They sounded good in all of those environments. The speakers are easy to work with because they come with Dupont connectors pre-installed on the end, making them easy to breadboard without any soldering. This greatly simplifies testing and prototyping. These are good quality speakers that are stable and easy to integrate into 3.3V or 5V low-voltage circuits. I give them 4 stars.

Bought for a project of mine and works just as intended. Good speaker quality

Ottimi x lavori hobbistici

Compré este par de mini altavoces para integrarlos en un proyecto de electrónica/caja arcade. Calidad de sonido: Para ser altavoces de 3 W, ofrecen una nitidez aceptable en voces y efectos. No esperes graves potentes debido a su tamaño, pero cumplen muy bien su cometido. Diseño y montaje: La caja de resonancia cerrada ayuda bastante a que el sonido no se escuche metálico o enlatado. Las pestañas de montaje facilitan fijarlos con tornillos dentro de cualquier chasis. Conexión: Los cables vienen con su conector listo para enganchar a placas de audio compatibles.

Very clear, no soldering required. Impressed!!

ihren Zweck erfüllen sie, gut verarbeitet, gerne wieder.

a bit tiny good sound over all
