About the Memory Board

Memory Board is an open source PCB design by esl-epfl, published on GitHub. It is a 6-layer board measuring 15.2 × 10.8 mm, with 11 components from 4 distinct parts.

Other key parts include the MX25U12832FZNI02-TR and MX25U25643GZ4I00-T. By type, the board carries 7 resistors, 2 ICs and 2 capacitors.

It belongs with the wearables designs in this gallery.

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.

Memory Board: common questions

How big is the Memory Board?

The Memory Board measures 15.2 × 10.8 mm, has 6 copper layers and is 0.8 mm thick.

How many components are on the Memory Board?

11 components, from 4 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Memory Board design files?

From the esl-epfl/X-MODs repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Memory Board design in my own project?

The repository has no license, so all rights stay with esl-epfl. Use it as a reference, and ask the author before reusing the design.
