Bluetooth 5.0 Wireless Lossless Audio Stereo Receive Es9018 Aptx-hd

1. Bluetooth audio receiver board adopts for CSR8675 chip solution Bluetooth digital audio signal reception, I2S digital signaltransmission to ES9018 chip decoding, output analog audio signal through dual op amp filter amplification output.2. Supports wireless Bluetooth reception and one AUX analog audio input for switching output. Lossless switching with relays will not have any effect on sound quality.3. The module defaults to AUX line mode, the switching mode is automatic switching, and Bluetooth is preferred.4.The module is a high-level version that supports the LDAC protocol and supports a sampling rate of 24bit/96khz, which exceeds the APTX-HD's 24-bit/48knz sampling rate.5. A DC single-supply power supply, wide voltage range DC 5V-32V, product design multi-stage voltage regulator, Bluetooth module, DAC chip, op amp chip are powered by independent power management chip, the op amp uses dual (positive and negative) 13V power supply, Fever level design.Product description:1. DC power input, red (+12V) is positive and black (GND) is negative. Support DC5V-32V, note: AC power cannot be used.2. AUX analog audio input, white line (INL) is the left channel, black (GND) is the audio ground, and red (INR) is the right channel. Note: The audio ground wire cannot be connected incorrectly.3. Audio output, white line (L-OUT) is the left channel, black (GND) is the audio ground, and red (R-OUT) is the right channel. Note: The audio ground wire cannot be connected incorrectly.4. The Bluetooth external antenna is buckled, and the antenna with the buckle is directly fastened, and the 2. 4G antenna can be used. The module must be installed in the gold M case and an external antenna must be added.Colour:blackMaterial:ABSSize:3.3*6.7*1cmPackage Contents:1 * decoding board1 * antennaOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
