STM32F103x8: common questions
What microcontroller does the STM32F103x8 use?
The STM32F103x8 is built around the LM555XN, from the STM32 family.
How big is the STM32F103x8 PCB?
The STM32F103x8 measures 74.4 × 61 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the STM32F103x8?
16 components, from 13 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 STM32F103x8 design files?
From the kinsy3015/Circuit_Design 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 STM32F103x8 design in my own project?
The repository has no license, so all rights stay with kinsy3015. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the STM32F103x8 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.
