From the project
A compact DSP development board for real-time embedded audio and sensing
This repository contains the hardware design files, pinout, and architectural documentation for the uDSP-Card, a small development board built around the XMOS XU316. Originally designed for a wearable ultrasonic sensing system, the board offers rich I/O and high-performance DSP capabilities at low power, making it ideal for audio, sensing, and real-time embedded tasks.
