FreeDSP-OCTAVIA
FreeDSP-OCTAVIA is an open source PCB design by freeDSP: a 4-layer, 178 × 99 mm board with 505 components (134 distinct parts). It is built around the TPS5430DDA, PCM1808QPWRQ1, GP1UXC41QS, PLR135-T10 and more. Filed under audio.
8ch Output ADAU1452/1466 DSP Board with Analog/COAX/OPT/USB/Raspberry-Pi Input
Version 1.2 is the latest commit. version 1.0 is evaluated and it worked. version 0.33j board requires some workarounds. version 0.33j_Fixed is a fixed design of 0.33j, But I recommend you build the latest version 1.2 or 1.1 The errata information is detailed below... https://github.com/freeDSP/freeDSP-OCTAVIA/wiki/Errata-and-Workarounds
