DESCRIPTION
 
 
 

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.

INTERFACES
FLEXIBLE I/O SUPPORTS DEVELOPMENT
TONE 13
Khadas aims to gradually realize the ideas and dreams of developers to help makers 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:
  • 1 30-pin FPC connector for 8-channel analog output expansion
  • Two 10-pin FPC connectors for OLED display and I2S expansio
Other:
  • 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.
