This product is finished board, a purchase of 5 or less does not accept the bargain, there is no free shipping service, no gifts, not supplied any USB wire lines, the buyer please do not ask these questions.
This product design and features:
1. Use XMOS latest U Series as the core processing USB to IIS / DSD,
2. With sampling instructions output instruction
3. Provide DSD_ON and MUTE output
4.XMOS chip 3.3 V power supply with ultra low noise ADP150 regulator chip
5, the circuit board through multiple versions proofing test, design optimization, the bottom is connected to a large area of paving design, few traces, crystal position very close to the XMOS, the external clock signal to reduce interference,
 
All audio lines are expanded matching resistor in series resistance, by an oscilloscope trace test, and strive to achieve the best signal quality.
6. The commodity large use MCLL as decoupling, each powered via LC filter are decoupling, HIFI design
7. Compatible Italy Amanero usb module size, I2S / DSD output pin correspondence.
8. The latest stable version of firmware and drivers:
