Hi-Res Audio Board Designed for Music Fanatic.
Tone Board is an amazing USB External HiFi Sound Card in Khadas Family. Its excellent performance and compatibility will take the listening experience to a whole new level. And that is just the beginning…
Inherit Khadas Consistent Breakthrough Design
We integrated XMOS advanced Multi-Core RISC architecture microcontroller and ESS flagship 32-Bit stereo mobile audio DAC ES9038Q2M in such a small PCB. At the same time, we selected three independent high performance OPA and four Ultra-Low phase jitter oscillator for our audio system.
The same as you think, each power supply path is powered by an independent, Ultra-Low noise CMOS linear regulator and the OPA was powered up to ±5.5V. There are a lot of examples like this，but in general，we try our best to get better performance through reasonable design.
Flexible Interfaces Support DIY Development.
Khadas aspires to help the makers grow by achieving their ideas and dreams step by step. Tone Board is the same. It has 2 RCAs for analog output @ 2.0Vrms and 1 RCA for S/PDIF in or out.
One 30-Pins FPC Connector for 8 Channels Analog Output Extension
Two 10-Pins FPC Connectors for OLED Display and I2S Extension
One 40-Pins Female header is used for connecting VIMs
One 20-Pins SMT Header for debugging XMOS and VIMs.
Of course, users can enjoy Tone Board via USB-C interface and Tone Board is an ideally choice for audio developers obviously. Another good news is Khadas new heatsink can fit with VIMs and Tone Board. It is very convenient for customers to develop and mold design so that the customized product realization ASAP.
