Beschreibung

BM83 Bluetooth Microphone & Speaker PCB / PCBA Kit

A two-board kit based on CreatorKanata’s open-source bowtie microphone and button speaker project, originally published as conan-style-voice-changer-mic-speaker. Supplied by DIYIPCB for wireless audio and wearable electronics development.

Main module and functions

BM83 Bluetooth audio module: used on both boards. The upstream microphone configuration uses HFP for audio capture, while the speaker configuration uses A2DP for playback. The microphone design includes a MEMS microphone; both designs provide battery-charging circuitry.

Typical uses

• Wearable Bluetooth microphone and compact wireless speaker experiments.
• Raspberry Pi audio-processing and voice-effect prototypes.
• Interactive props, maker demonstrations and wireless-audio learning projects.

Voice changing takes place on an external Raspberry Pi 5 running appropriate software. These two boards are audio peripherals, not a standalone voice changer. Firmware/profile configuration, Bluetooth setup and host software are required. Translation is described as planned in the upstream project and is not a supplied function.

Kit contents and pricing

PCBA is made to order; shipping transit time is additional. Both options exclude Raspberry Pi 5, batteries, external speaker driver, cases, cables and other external accessories. The PCB kit contains no components or BM83 modules. Contact DIYIPCB to agree any module programming, profile configuration or test requirements.
