From the project

a small, modular and affordable DSP Module

The goal of this Project is to create a line-up of small DSP modules, centred around an Analog Devices ADAU1463/67. This Chip is easy to program with Sigma Studio, a node based development environment and pretty powerful for its price.

Current status: - Dual: Rev 1.1: Layout finished, functionality has to be validated. - Maxi: Rev 1.0 functional, layout of rev 2.0 finished and production ready, has to be evaluated. AES17 audio measurements of rev 1.0 available. - Mini: Nothing done yet. - Micro: Nothing done yet. - Digi: Nothing done yet.
