BM-3086 is a highly integrated single-chip Bluetooth v5.4, audio and programmable application module. It includes high-performance, analog, and digital audio codes, advanced power management, Li-ion battery charger, light-emitting diode (LED) drivers, and flexible interfaces incuding inter-integrated circuit sound (I2S), inter-integrated circuit interface (I2C), universal asynchronous receiver transmitter (UART), and programmable input/output (PIO).

The system-on-chip architecture design of the module makes a much smaller space and minimal cost and simplifies the whole system design.
