The KiCad project lives in the OpenElectronicsLab/OpenHardwareHolterMonitor repository on GitHub; these links point at the commit this page was built from.

OpenHardwareHolterMonitor: common questions

What microcontroller does the OpenHardwareHolterMonitor use?

The OpenHardwareHolterMonitor is built around the ESP-32, from the ESP32 family.

How big is the OpenHardwareHolterMonitor PCB?

The OpenHardwareHolterMonitor measures 131 × 80 mm, has 1 copper layer and is 1.6 mm thick.

How many components are on the OpenHardwareHolterMonitor?

145 components, from 48 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 OpenHardwareHolterMonitor design files?

From the OpenElectronicsLab/OpenHardwareHolterMonitor repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the OpenHardwareHolterMonitor design in my own project?

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

Can I test firmware for the OpenHardwareHolterMonitor without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
