From the project
Modular hardware platform based on the RISC-V X-HEEP family architecture developed at ESL, targeting ultra-low-power consumption and miniaturization, facilitating the creation of wearable devices for clinical trials
A collection of compact, power-efficient PCB modules designed for rapid prototyping and development of wearable healthcare devices, with a focus on biosignal acquisition.
X-MODs provides a modular hardware approach that bridges the gap between fully custom designs and off-the-shelf solutions. The system consists of four specialized modules and their corresponding debug boards, enabling quick prototyping while maintaining the small form factor required for wearable applications.
