FLC-BTM061 is a HCI BT module with a high cost performance with independent I2S/PCM interface audio encoder/decoder, which can provide OEM with certified embedded BT audio solutions. The module supports BT2.1+EDR transmission and HCI interface. The audio encoder and decoder can connect to stereo Hi-Fi DAC and stereo ADC through I2S/PCM interface, which can realize replay and recording functions.
With the BT protocol stack software independently developed by Flairmicro, designers can easily design different application programs to support various profiles, such as HS/HF, A2DP, AVRCP, OPP, DUN and SPP. The module supports EDR, with a transmission speed as high as 4Mbps.
