About the Eurorack pmod PCB

Eurorack pmod is an open source PCB design by apfaudio, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 35 × 110 mm, with 116 components from 34 distinct parts.

Other key parts include the AK4619VN, C6963, C141380, C2061498 and C139380. By type, the board carries 44 resistors, 29 capacitors, 18 diodes, 10 connectors, 8 ICs and 6 inductors.

It belongs with the audio designs in this gallery.

From the project

A eurorack-friendly audio frontend compatible with many FPGA boards, based on the AK4619VN audio CODEC.

Note: this repository contains Verilog examples for using Eurorack-PMOD with different FPGA boards. If you are trying to pair it with Tiliqua or Amaranth HDL, see the quickstart guide there

Eurorack PMOD is an open hardware Eurorack module that plugs directly into many FPGA boards, which makes it easy to combine the world of FPGAs and hardware electronic music synthesis.
