Iv flow monitor: common questions

What microcontroller does the Iv flow monitor use?

The Iv flow monitor is built around the STM32G071C8T6, from the STM32 family.

How big is the Iv flow monitor PCB?

The Iv flow monitor measures 50 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Iv flow monitor?

53 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 Iv flow monitor design files?

From the Global-Health-Engineering/iv-flow-monitor 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 Iv flow monitor design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which Global-Health-Engineering chose for the repository.

Can I test firmware for the Iv flow monitor 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.
