ECG-Simulator: common questions

What microcontroller does the ECG-Simulator use?

The ECG-Simulator is built around the ATmega328-PU, from the AVR/Arduino family.

How big is the ECG-Simulator PCB?

The ECG-Simulator measures 67.3 × 48.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ECG-Simulator?

41 components, from 33 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 ECG-Simulator design files?

From the JohanSmets/ECG-Simulator repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ECG-Simulator design in my own project?

Yes, under the terms of its GPL-3.0 license, which JohanSmets chose for the repository.

Can I test firmware for the ECG-Simulator 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.
