The demand for reliable and future-proofed audio networking is growing rapidly with the adoption of Milan. Manufacturers face a challenge in adopting Milan while keeping focused on the core functionality of their product. This is where Sienda offers a significant time and cost saving through a drop-in Milan hardware module.

VITRA is a tiny and powerful ready-to-go system-on-module that enables manufacturers to implement full Milan functionality quickly and easily. It implements Sienda’s TSN solution, preferred by prestigious names in the pro-audio industry.

  • Milan network connectivity via 2 Gigabit Ethernet interfaces

  • 32 Input + 32 Output digital audio channels via I2S/TDM

  • 8 x 8-Channel Milan streams

  • Available as system-on-module or ‘Soft-SoM’ to implement directly into your design

  • Highly configurable peripherals including I2C, SPI, USB, UART, word clock, and more

The consistent availability of components that power your products is critical. While we can’t control the availability of each individual component, Sienda are dedicated to providing solutions that ensure uninterrupted delivery to your customers.

Here’s our commitment to availability for your peace of mind:

Direct Integration Option
We offer the option to seamlessly integrate our designs directly onto your PCB, eliminating the need to purchase a physical module from us.

Built-In Alternatives
Our hardware and software designs are developed with alternative components in mind, ensuring flexibility and adaptability to changing supply conditions. Our core software stack runs on almost any platform.

Full Design Transparency
If for any reason Sienda is unable to supply modules, we will provide complete design files for our hardware, enabling you to manufacture them independently.

VITRA is in currently in development.
Pricing information will be released in Q3 2025.
