This is a usb audio interface made with cheap stm32f401rbt6 chip.It's easy to buy in china(compare to atmel or ti or nxp).
1,async clock with external clocks input to stm32f4 series i2s_ckin pin, cpld device not required anymore.(see the schemaitcs for more infomation).
2,support 24bit 44.1/48/88.2/96k audio streaming formats.
3,working with "xmos stereo driver",windows build-in driver,linux build-in driver.
please note Any Commercial Use Prohibited!! i share it only for your DIY.
