Pcb design: common questions
What microcontroller does the Pcb design use?
The Pcb design is built around the STM32F072CBT6, from the STM32 family.
How big is the Pcb design?
The Pcb design measures 228.6 × 79.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pcb design?
116 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pcb design design files?
From the 3sculape/pcb-design repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pcb design design in my own project?
The repository has no license, so all rights stay with 3sculape. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pcb design 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.
