in the past few months we have worked very hard on a new shield for RPIs/SBCs.
Basically the main idea belongs to Ian’s. His hardware is actually superior to ours , mostly in the way he implemented the clocks and to the attention of the detail (like mounting xtals on a pcb supported by elastics ). So we credit Ian’s idea and his great design.
Our hardware/soft is not a copy , its an implementation of the same idea. We use a FPGA and sram to buffer the DATA and we reclock bclk/mclk outside the FPGA using NDK (or Crystek) . The board has an eprom but its not HAT complaint (because of the space). FCC will be available for the board.
Main reason for making the board was to try to correct the audio clocks of SBCs and bring high quality audio to anyone that has an SBC around…for a great price.
Please let me know your thoughts on this…
