Tone Board is a USB external HiFi sound card specially developed for Khadas VIMs by Khadas brand series products. Its superior performance and compatibility take the audiovisual experience to a whole new level. We integrated the advanced XMOS multi-core RISC microcontroller 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. As you can imagine, 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 design.
- 1 30-pin FPC connector for 8-channel analog output expansion
- Two 10-pin FPC connectors for OLED display and I2S expansio
- One 40-pin female connector for VIM
- A 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.
