Questions

How big is the HW template PCB?

It measures 63.5 × 118.1 mm and has 4 copper layers, 1.6 mm thick.

What parts does the HW template use?

88 parts, built around the AD8232ACPZ-R7. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the HW template KiCad files?

From the Tommy270502/PM4 repository on GitHub, at the commit this page was made from: the board is 3_Hardware/1_HW_template_2026_02_11_v10/HW_template.kicad_pcb and its schematic 3_Hardware/1_HW_template_2026_02_11_v10/ECG.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the HW template design in my own project?

Its repository states no licence, so its author keeps all rights: ask Tommy270502 before reusing the design.
