Khadas Tone Board High Resolution Audio Board VIMs, Compatible(Generic Edition) for Desktop PCs/Laptop PCs/Edge, Raspberry PIS and Other SBCs/All Other Devices via Included USB-C to USB-A 2.0 Cable
XMOS: XU208-128-QF48, Eeight Cores, Core Share up to 500 MIPS; ES9038Q2M 32-Bit Stereo Mobile Audio DAC.
Compatibility: Windows PC, Mac OS, Android, Linux PC, Volumio, LibreELEC, and Other SBCs. The XMOS USB Audio to ensure a rock-solid connection. We selected to use the XMOS XU208 microcontroller for its stability, powerful functionality,and its reliability. You can be sure that the Tone Board will just work when connected to most audio sources,such as computers and mobile media terminals.
Different Versions: VIMs Versions (Khadas Tone + VIMs) connected through GPIO Pins; Generic Edition won't have GPIO Pins on board.
Extension: One 30-Pins FPC Connector for 8 Channels Analog Output Extension; Two 10-Pins FPC Connectors for OLED Display and I2S Extension; VIMs Version also have 40-Pins Female header connecting with VIMS and 20-Pins SMT Header for debugging XMOS and VIMs.
Ultra-low Phase Noise Clock Jitter: The SiTime ultra performance oscillator SiT820&8209 series with just 0.5ps phase jitter and output frequency stability as low as ± 10PPM. We chose it as a reference clock in our audio system so that the data clock jitter < 30ps.

Product Information
Product 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.
Two Versions-Generic and VIM editions
Khadas aims to gradually realize the ideas and dreams of makers to help them grow. The two versions of the Tone Board's RCA output interface are the same, both have 2 RCA for analog output @ 2.0Vrms, and 1 RCA for S/PDIF input or output.
Expansion:
x1 30-pin FPC connector for 8-channel analog output expansion
x2 10-pin FPC connectors for OLED display and I2S expansion
Other:
x1 40-pin female connector for VIM
x1 20-pin SMT header for debugging XMOS and VIM.
Users can directly connect their Tone Board to the PC via the USB-C interface, and the Tone Board is the ideal choice for audio developers. Khadas' New VIM Heatsink can also be used with VIM and Tone Board.
