Philcoba: common questions
What microcontroller does the Philcoba use?
The Philcoba is built around the STM32F103C8T6, from the STM32 family.
How big is the Philcoba PCB?
The Philcoba measures 46 × 28 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Philcoba?
30 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the Philcoba design files?
From the mekatronik-achmadi/example_collection repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Philcoba design in my own project?
The repository has no license, so all rights stay with mekatronik-achmadi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Philcoba 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.
