JC-303 Bluetooth DAC Board BT5.0 Bluetooth Audio Receiver Board 16bit/48KHz White w/o Antenna Kit

JC-303 Bluetooth DAC Board BT5.0 Bluetooth Audio Receiver Board 16bit/48KHz White w/o Antenna Kit

Features:
- 5.0 HiFi Bluetooth chip transmits data to analog amplifiers with high speed and achieves wireless HiFi sound quality. It is suitable for modifying amplifier, DIY board, and preamplifier processor etc.

- Traditional wired transmission is converted to wireless Bluetooth transmission. The module uses high-fidelity Bluetooth 5.0 chip. The Bluetooth 5.0 high-speed transmission ensures that the audio data is transmitted to the analog amplifier without loss, in order to achieve wireless HIFI level sound quality.

- The module supports 16bit/48KHz lossless reception and the sound quality level reaches the CD level. Using PCM5102A decoding chip, it can provide analog audio signal for preamplifier or for power amplifier, no extra DAC decoder needed.

- The module supports AUX input to facilitate external linear audio. Between the AUX and Bluetooth, imported NEC high-precision relays are used for switching. The AUX input is switched directly by the relay without any chip processing, ensuring lossless output of AUX audio to your amplifier.

- Original components and environmentally friendly process ensure excellent performance and longer life span. It is built with quality filter capacitors.


①DC Power Supply Input Port: GND for the power supply negative, +12 V for the power supply positive. Wide voltage: 6-36V
②AUX Audio Interface: LINE_INR: right-channel input, GND: common ground wire, LINE_INL: left-channel input
③Audio Output Port: R_OUT: right-channel output, GND: common ground wire, L_OUT: left-channel output
④Audio Switching Relay, NEC original import ensure high-quality transmission and long life span
⑤On-board Bluetooth Antenna Port: Used to install an external 2.4GHz antenna to increase Bluetooth signal reception. Its transmission distance is up to 20m in open space without obstacles. If the receiver board is installed to a metal housing, an external 2.4GHz antenna is needed.
