The current Qualcomm flagship Bluetooth chip 5171 is Bluetooth version 5.3, support for all current Bluetooth audio formats! 5125 is Bluetooth 5.1 mainstream high-end, support for LDAC APTX HD, etc., sub-high-end 3034 module, support for APTXHD does not support LDAC , the board has a black blue green, the color is sent at random!
Support A2DP, AVRCP, HFP, AAC, I2S, etc. with 16M SPI FLASH memory chip.
Many people need to add bluetooth capability to their amplifiers, but a bluetooth board won't solve the problem because the amplifier itself has analog inputs. This board solves the problem very well. Increased analog input port, when the phone Bluetooth is on, the amplifier outputs the phone's Bluetooth audio. When the phone's Bluetooth is disconnected, it automatically connects to the original analog input. This product supports Bluetooth 5.0, low transmission delay, support for a variety of lossless format transmission, the key is the output of the TI advanced decoder chip PCM5102, than the general toy level Bluetooth board regardless of the level of detail, high and low frequency extension are much better! PCB size: 64X63MM without DC interface Voltage range: AC 6-12V, or DC 7-14V. 1 decoding part of the latest U.S. BB's new PCM5101, 5102 decoding core, is a 24bit stereo audio digital-to-analog converter chip (DAC), the dynamic range of 112dB, distortion -93db, direct output of 2.1V RMS audio voltage, high-frequency burr, low-frequency powerful, good potential. 2 Relay non-destructive switching signals, gold-plated RCA inputs and outputs Main board package.
Recommended reasons:
1: 100% full machine chip installation, reliability and stability is much higher
2: the use of samsung original chip resistor capacitor
3: Japan Takamizawa original signal relay
4: with reverse protection circuit (of course, do not easily reverse)
Recommended supply voltage: DC 6-18V current 100mA
