The Khadas Tone Board can be used as a typical stand-alone USB DAC. It may be used as a bare-board or may be mounted into a full metal or plastic enclosure that could be molded or CNCd, with a custom company logo printed or embossed on it. It also features five M2 clearance holes and three RCA rings for easy mounting to cases of any size or thickness. The generic Tone Board KTONE-G-001 is the most ideal for this solution, as it is the thinnest in design.
