The KiCad project lives in the DanielMartensson/OpenSourceLogger-Web repository on GitHub; these links point at the commit this page was built from.

OpenSourceLogger-Web: common questions

What microcontroller does the OpenSourceLogger-Web use?

The OpenSourceLogger-Web is built around the STM32F373CCT6, from the STM32 family.

How big is the OpenSourceLogger-Web PCB?

The OpenSourceLogger-Web measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OpenSourceLogger-Web?

116 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the OpenSourceLogger-Web design files?

From the DanielMartensson/OpenSourceLogger-Web repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the OpenSourceLogger-Web design in my own project?

Yes, under the terms of its MIT license, which DanielMartensson chose for the repository.

Can I test firmware for the OpenSourceLogger-Web without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
