Description
The Khadas Tone Board is a USB external Hi-Fi sound card specially developed for Khadas VIM SBCs by Khadas. Its superior performance and compatibility take the audio/visual experience to a whole new level. We integrated the advanced XMOS multi-core RISC micro-controller and ESS flagship 32-bit stereo mobile audio DAC ES9038Q2M into a small PCB. At the same time, we selected three independent high-performance OPAs and four ultra-low phase jitter oscillators for the audio system. Each power path is controlled by a separate ultra-low noise CMOS linear regulator with an OPA of ± 5.5V. In addition to the powerful hardware configuration, we also maximize the performance through excellent PCB design.
