BM83SM1-00TA Overview
A Bluetooth audio module is a wireless connectivity and embedded-control subsystem that adds Bluetooth communication to an audio product without requiring a discrete radio design. In the broader product hierarchy, this module is a Bluetooth transceiver module, an RF and wireless module, and an embedded audio bridge. It can receive audio through auxiliary input or I2S and stream that audio to up to two paired Bluetooth sink devices, making it useful for dongle-style designs and products without native Bluetooth.
The BM83SM1-00TA is qualified for Bluetooth 5.0 and supports Classic BR/EDR as well as BLE. Its profile set covers hands-free, headset, advanced audio distribution, serial port, audio/video remote control, and phone-book access functions. A2DP source and sink capability supports both sending audio to headphones or speakers and receiving audio from a paired source. The module also supports AAC and SBC decoding, broad protocol support, and GATT/GAP services.
The BM83 family is intended for stereo-audio connectivity in compact embedded products. Its integrated module approach reduces the need to design and qualify a separate RF radio, antenna structure, audio interface, and Bluetooth protocol stack on the host PCB. Firmware configuration remains important: the BM83SM1-00Tx variant implements A2DP source capability using Audio Transceiver firmware, so host firmware and command sequences must match the intended audio role.
Typical uses include Bluetooth audio dongles, wireless speakers, headphones, source accessories, home-audio adapters, and embedded audio gateways. The verified data confirms the frequency range, Bluetooth version, protocol profiles, audio inputs, and dual-sink streaming behavior. Electrical limits, pin names, supply voltage, antenna requirements, and package dimensions should be taken from the manufacturer datasheet before PCB release.
PCB implementation must preserve the module’s required antenna clearance, ground connectivity, audio routing, and power decoupling. Keep RF-sensitive and audio-sensitive traces away from noisy switching paths where practical, provide the manufacturer-specified bypass capacitors close to the supply pins, and follow the reference layout for antenna and exposed grounding. Validate RF performance with the intended enclosure because plastic, cables, grounding, and nearby structures can change the installed antenna behavior.
This product-data page combines the verified Microchip feature description, distributor identification, and cross-reference search results. It distinguishes confirmed facts from missing electrical details and avoids inventing a pinout or package drawing that was not present in the supplied sources. For production use, compare the selected BM83SM1 variant, firmware image, regulatory requirements, and supplier availability before committing the design.

Typical Applications
BM83SM1-00TA is suitable for 6 applications: Bluetooth Audio Dongle, Wireless Speaker Source Interface, Bluetooth Headphone Accessory, Embedded Audio Gateway, Wireless Home-Audio Adapter, Bluetooth Control and Service Access.
Bluetooth Audio Dongle
BM83SM1-00TA fits a dongle that adds wireless audio to equipment without native Bluetooth connectivity. The verified Microchip material describes BM83SM1-00Tx Audio Transceiver firmware, Aux-in or I2S audio reception, and streaming to as many as two paired Bluetooth sink devices. A host processor can select the required profile and route incoming audio into the module, while the module handles Bluetooth pairing and A2DP streaming. The design must still provide a suitable power supply, antenna implementation, audio conditioning, and firmware integration. Validate pairing behavior, latency, codec support, and enclosure effects because the supplied evidence does not specify dongle-level timing or RF test results.
Recommended
Wireless Speaker Source Interface
BM83SM1-00TA can provide a Bluetooth audio-source path for a wireless speaker or powered speaker accessory. Its verified A2DP 1.3 source capability allows the module to send audio toward a paired Bluetooth sink, while the module also supports sink operation for broader product flexibility. The speaker host can feed audio through Aux-in or I2S according to the system architecture, then use SPP or control commands for configuration and AVRCP-related remote control. Because the module is a complete embedded wireless subsystem, the host design can avoid implementing a separate Bluetooth radio stack. Validate codec negotiation, channel routing, startup behavior, and thermal performance in the final enclosure.
Recommended
Bluetooth Headphone Accessory
BM83SM1-00TA is suitable for an accessory that adds Bluetooth audio connectivity to headphones, speakers, or a home-audio adapter. The verified feature set includes Bluetooth 5.0, Classic BR/EDR, BLE, HFP 1.7, HSP 1.2, A2DP 1.3 source/sink, SPP 1.2, AVRCP 1.6, and PBAP 1.2. That combination supports audio streaming, hands-free or headset-oriented use, remote control, and service access without requiring a separate host Bluetooth controller. The product must still select the correct A2DP role and firmware configuration. Test microphone and control paths separately from the audio stream, and verify that the intended paired devices implement the required profiles.
Recommended
Embedded Audio Gateway
BM83SM1-00TA can act as a wireless bridge in an embedded audio gateway that receives local audio and distributes it through Bluetooth. Aux-in or I2S input gives the gateway a path from an audio source, while the verified dual-sink description allows streaming to as many as two paired Bluetooth sink devices. This is useful for prototyping a bridge between an existing sound system and wireless headphones or speakers. The host must control pairing, source selection, volume policy, and reconnection behavior. Designers should verify that the audio source bandwidth is appropriate for Bluetooth codec conditions and that the selected firmware supports the intended A2DP source workflow.
Recommended
Wireless Home-Audio Adapter
BM83SM1-00TA is a practical candidate for a wireless home-audio adapter that converts a wired audio path into Bluetooth connectivity. Its verified 2.402 GHz to 2.48 GHz operating range, Bluetooth 5.0 qualification, and A2DP support provide the core wireless function for speakers, headphones, and secondary audio endpoints. The module can receive audio through Aux-in or I2S and stream it to paired sinks. A production adapter still needs analog or digital audio conditioning, power regulation, decoupling, an antenna keepout region, enclosure tuning, and application firmware. Confirm regulatory obligations and validate coexistence with other wireless systems before release.
Recommended
Bluetooth Control and Service Access
BM83SM1-00TA can add Bluetooth control and service access to an embedded audio product through its supported Classic profiles. SPP 1.2 provides a serial-port path for commands or data, AVRCP 1.6 supports remote-control workflows, and PBAP 1.2 supports phone-book access where the host product requires it. This makes the module useful in accessories that need more than basic audio streaming, such as configurable speakers or connected audio control panels. The host software must define command framing, authentication where applicable, profile activation, and fallback behavior. Test interoperability with the phones, headsets, and control applications targeted by the product because profile support alone does not guarantee identical user experience across platforms.

Design Notes
Use the official BM83 package drawing and reference layout before placing the module. Preserve the manufacturer-required antenna keepout, route the RF connection according to the datasheet, and place input, output, and bypass capacitors close to their associated pins. The supplied sources identify a 50-lead module but do not provide the complete pin table, so do not infer pad functions or exposed-ground requirements from the distributor descriptions.
Treat the 2.402 GHz to 2.48 GHz RF section as a constrained signal path. Keep switching regulators, high-current audio outputs, digital clocks, and long copper structures away from the antenna region, and follow the manufacturer’s recommended ground and return-current arrangement. An enclosure, cable, or neighboring PCB can change antenna performance; verify radiated emissions, conducted emissions, and wireless range in the final mechanical assembly.
Route Aux-in or I2S audio with short, controlled-impedance paths and keep analog audio, digital control, and RF activity separated where practical. Confirm the selected firmware’s expected audio format, clocking, and channel arrangement rather than assuming that all BM83 variants use identical I2S behavior. If A2DP source mode is used, validate codec negotiation and dual-sink playback with the actual paired devices.
Do not treat BM83SM1-00TB, BM83SM1-00AA, or BM83SM1-00AB as automatic replacements. The supplied search results identify them as related candidates but do not establish identical pin assignments, electrical limits, profile behavior, or firmware. Before substitution, compare the official BM83 family documentation, package drawings, antenna implementation, supply requirements, audio interfaces, and the host firmware command set.
Compliance Information
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Regulatory certification and product-specific compliance must be confirmed with Microchip and the selected supplier.
