About the AD8232 Board

AD8232 Board is an open source PCB design by EObianom, published on GitHub under the CC-BY-NC-4.0 license. It is a 4-layer board measuring 25.4 × 17.7 mm, with 26 components from 14 distinct parts.

Other key parts include the AD8232. By type, the board carries 15 resistors, 7 capacitors, 2 connectors, 1 IC and 1 diode.

It belongs with the wearables designs in this gallery.

From the project

A compact, production-ready ECG front-end built around the AD8232, designed with KiCAD for seamless integration into wearable and embedded systems. Small in size, deliberate in design, and ready to manufacture.

This project implements a highly miniaturised ECG acquisition circuit with a footprint of just 25mm × 17.7mm. It is engineered for space-constrained applications where traditional breakout boards fall short. Unlike conventional AD8232 modules, this design eliminates the bulky 3.5mm audio jack, enabling direct electrode interfacing and tighter system integration. The result is a clean, flexible…
