According to current statistics, over 1.6 million people die in India due to a lack of access to health care. Most of these cases occur in rural areas of the developing nations including India. Difficulty in accessing immediate health care is important for the proper treatment and recovery of many diseases. Heart diseases come under a category of conditions that need to be detected early for proper recovery and treatment.

PORTABLE-ECG: common questions

What microcontroller does the PORTABLE-ECG use?

The PORTABLE-ECG is built around the ATMEGA328PB-A, from the AVR/Arduino family.

How big is the PORTABLE-ECG PCB?

The PORTABLE-ECG measures 64.8 × 25.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PORTABLE-ECG?

80 components, from 47 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 PORTABLE-ECG design files?

From the jeis-aj/PORTABLE-ECG 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 PORTABLE-ECG design in my own project?

Yes, under the terms of its MIT license, which jeis-aj chose for the repository.

Can I test firmware for the PORTABLE-ECG without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
