66AK2Gx (K2G) audio daughter card


Order now


The K2G audio daughter card is designed to work in conjunction with the K2G general-purpose EVM (EVMK2G) or EVMK2GX and the EVMK2G or EVMK2GX is required for audio daughter card operation.  The daughter card allows users to develop multichannel audio applications such as A/V receivers, soundbars, automotive amplifier systems and mixing consoles based on the 66AKG2G02 DSP + Arm® processor SoC.

  • Audio expansion compatible with the K2G general-purpose EVM
  • Eight channels of analog input
  • Sixteen channels of analog output
  • S/PDIF input (optical or coaxial)
  • S/PDIF output (coaxial)
  • I2S header for external I/O (HDMI, etc.)

  • Assembled Audio DC hardware
  • Mechanical standoffs
  • Quick start guide
  • Mechanical instruction document 1 (assemble standoffs to the hardware
  • Mechancial instruction document 2 (integration of Audio DC with EVMK2G)
  • Warranty notice
