KiCad SolderingIron: common questions
What microcontroller does the KiCad SolderingIron use?
The KiCad SolderingIron is built around the STM32F103C8Tx, from the STM32 family.
How big is the KiCad SolderingIron PCB?
The KiCad SolderingIron measures 100 × 57 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the KiCad SolderingIron?
66 components, from 41 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 KiCad SolderingIron design files?
From the MikolajPieklo/KiCad_SolderingIron 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 KiCad SolderingIron design in my own project?
The repository has no license, so all rights stay with MikolajPieklo. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the KiCad SolderingIron 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.
