CurrentSensingCircuit: common questions

What microcontroller does the CurrentSensingCircuit use?

The CurrentSensingCircuit is built around the STM32F103C8Tx, from the STM32 family.

How big is the CurrentSensingCircuit PCB?

The CurrentSensingCircuit measures 100 × 50 mm, has 4 copper layers and is 1.565 mm thick.

How many components are on the CurrentSensingCircuit?

77 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the CurrentSensingCircuit design files?

From the Michalek007/CurrentSensingCircuit repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CurrentSensingCircuit design in my own project?

The repository has no license, so all rights stay with Michalek007. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CurrentSensingCircuit 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.
