Just a quick update, have finished various layout changes. Just need to produce manufacturing data, which will likely show a few issues that need tweaking before sending them off.
New designs are:
CoreOne Rev 2.0 - XMOS200 based board with Ethernet, USB, I2S, I2C, SPI. This is simplified over my first attempt, as the last version was very cramped and easy to knock off components you just fitted during build. Also modified the thermal pad so should be easy to solder with a soldering iron, and hopefully retain electrical performance.
An AK4458 DAC - same style as the existing ADAU1966 DAC but only 8 channels.
Also updates to the ADAU1966 DAC board and the ADAU1452 DSP board.
Any new/modified designs are now in KiCad 5.0.0 which is a good upgrade over version 4. I will be updating other designs so they are all in version 5 to keep things consistent.
