This product have 2 options:
Bundle 1 : only board(without case) $28.5
Bundle 2 : Finished product(with case) $34.5
Parameters:
1: Bluetooth-compatible version
Others:Bluetooth-compatible 2 or 3, dare not publish Bluetooth version.
2: the CSR8675 Bluetooth-compatible module in the UK supports APTX transmission. The advantage of supporting APTX HDaptX is that it can play 16-bit/44.1kHz audio in the way of music transmission. However, because aptX uses compression to reduce the delay of audio encoding, it can only bring "CD like sound quality" instead of real "CD level sound quality".
The emergence of aptX HD is related to the popularity of high definition audio, which supports up to 24-bit/48kHz audio, that is, we will be able to listen to sound quality music with wireless devices. Compared to the traditional aptX 352kbps ratio, aptX HD has more advantages than 576kbps bit rate.
3: the input and output of the signal is all used for the firing element.
Others: use common components and dare not expose internal pictures.
4: digital output has plastic chip and digital isolation transformer.
Others: no this function
6: coaxial and optical fiber output.
8: original software development, with its own Bluetooth-compatible name
Other: use general software, poor stability
9: multi-channel independent voltage regulator function +CLC filter, external phone charger can be
The operation is very simple. After the mobile phone detects the Bluetooth device, press the pairing.
PCB size: 80X60MM
Shell size: 68X20.5X86MM
Pure digital reception, similar products are received analog signals and then turn digital, the British CSR8675 chip directly output digital signal, Bluetooth-compatible to SPDIF digital output function. Bluetooth-compatible version 5. Software that is independently developed. A fever design and feverish material. CSR8670 only supports APTX, 16BIT transmission. CS8675 supports native 24BIT support APTX-HD
