FAQs

  • How to extend to 8 channel audio
    XMOS support 8 channels analog lineout, and Tone Board DAC(ES9038Q2M) has already used 2 channels. Users can add DAC for 8-channel expansion.

Hi, Just purchased a Tone board. had following questions

  1. Can this be used with wandboard running debian with USB-2 type A port?
  2. Do I need to cut off the powersupply from USB if I need to use an independent power supply
  3. Do I need to update firmware etc - are there instructions?
