Overview
Yahboom 3070/3525 micro speaker modules are designed for compact smart devices and DIY electronics such as K230 vision modules, smart cars, and programmable robots. Three speaker options are available, including a 3525 version labeled as special for the K230 vision module, with 2-pin connectors for easy integration.
Key Features
- Three versions available: 3070 Speaker (PH2.0-2Pin), 3525 Speaker (PH2.0-2Pin), and 3525 Speaker (GH1.25-2Pin, special for K230 vision module).
- Ultra-thin 3525 form factor: 35*25*6.2mm, 8g.
- Rated working power: 3W (all models).
- Working impedance: 4Ω±15% (all models).
- Frequency range: 0~20KHz (all models).
-
Multiple installation methods:
- 3525 speakers: adhesive backing sticking; magnetic sticking
- 3070 speakers: screw brass post mounting (screw hole mounting)
- Driver resources provided: MSPM0/STM32 driver tutorials and a datasheet are referenced for this speaker series.

Details

Choose from three compact speaker options: 3070 (PH2.0), 3525 (PH2.0), or 3525 GH1.25 for K230 vision modules.

A quick spec comparison helps match the connector, size, and cable length to your board and enclosure.


Multiple mounting methods simplify integration—stick the 3525 in place or bolt the 3070 to a chassis using its screw posts.

Ideal for adding audio output to K230 vision projects, DIY robots, and smart car builds.

Driver tutorials and a datasheet are provided to speed up integration with MSPM0 or STM32 platforms.
