2.4GHz bluetooth audio module with TWS
The module is a Bluetooth Stereo module with fully-certified Bluetooth® Version 5.0 (BDR/EDR) for who wants to add Bluetooth® wireless audio and voice applications to products. This Bluetooth module provides a complete wireless solution with Bluetooth stack, integrated antenna, and worldwide radio certifications in a compact surface mount package, 29x15x2.5 mm(+/-5%). This stereo module built-in Li-Ion charger and contain a digital audio interface. It supports A2DP v1.3, AVRCP v1.6, HFP v1.7, HID v1.1, AVCTP v1.4, AVDTP v1.3, and SPP v1.2 profile. Note that the customer must connect their own external analog CODEC/DSP amplifier and MCU for audio output.
The module module is a low power consumption, highly integrated Bluetooth system as an audio module. It integrates a high performance antenna, crystal and Bluetooth chip, which included RF transceiver, baseband processor, FLASH memory controller, multiple analog and digital peripherals, and a Bluetooth software stack including the audio, voice, and SPP profiles.
The cache based architecture enables full programmability with an SIP 8M FLASH memory device and can be used for both control and multimedia hybrid applications. The internal dual stereo ADC converts stereo analog input to digital signals that can be processed with a digital equalizer. Hardware realizations of the equalizer offload the MCU making the chip ideal for low power headset applications.
The module incorporates on-chip power management with linear and switch-mode buck regulators and also includes a 220 mA internal battery charge controller to further reduce external bill of material (BOM) costs.
