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?

• Plug eurorack-pmod into an FPGA development board of your choice. Here is a list of boards already supported by the examples.
• Get started with some example DSP cores. Examples include calibration, sampling, effects, synthesis sources and so on. The design files can be synthesized to a bitstream using Yosys' oss-cad-suite.

technical

• 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.
