get started in FPGA-based audio synthesis

eurorack-pmod is a certified open hardware Eurorack module that plugs directly into many FPGA boards. Find code examples and follow module development on GitHub.


How does it work?


  • 3HP module compatible with modular synthesizer systems.
    • Module depth is 35mm with both ribbon cables attached.
  • PMOD connector compatible with many FPGA development boards.
  • 8 (4 in + 4 out) DC-coupled audio channels, 192KHz / 32bit sampling supported.
  • PWM-controlled, user-programmable red/green LEDs on each output channel.
  • Jack insertion detection on input & output jacks.
  • Calibration EEPROM for unique ID and storing calibration data.
  • [new!] Touch and proximity sensing on all unused jacks as an extra input method.
