ADAU1701 DSP Guitar Pedal Platform

ADAU1701 DSP Guitar Pedal Platform

Programmable DSP platform for custom digital guitar effects.
Based on the ADAU1701 SigmaDSP, this pedal-format board is designed for effect development, prototyping, and production-oriented pedal designs with predictable signal behavior and low latency.

The ADAU1701 DSP Guitar Pedal Platform provides a stable hardware base for building compressors, dynamics processors, modulation effects, delays, distortion experiments, and other real-time audio effects. The design combines a proven SigmaDSP core with a pedal-oriented analog front end, allowing controlled signal levels and repeatable results suitable for serious pedal development.

The platform is designed for use with Analog Devices SigmaStudio, enabling full control over signal flow and processing without firmware development.

Platform highlights

• ADAU1701 SigmaDSP core
• Pedal-oriented hardware architecture
• Designed for use with SigmaStudio
• Low-latency real-time processing
• Suitable for prototyping and small-batch production
• Compatible with standard stompbox wiring conventions

Electrical and audio specifications

• External power supply: 9 V DC (standard pedal supply)
• Internal DSP supply: 3.3 V
• Audio input: unbalanced mono, instrument / pedal level
• Maximum input signal: approx. 2 Vpp
• Audio output: unbalanced mono or stereo, low-impedance buffered output

Assembly note
Audio jacks, DC power jack, and the 3PDT footswitch are intended to be soldered by the user to allow flexible enclosure and wiring options.

Intended audience

• Guitar pedal designers
• DSP developers working with SigmaDSP
• Builders creating custom or small-batch effects

Requires external programming via SigmaStudio.
