Stm32-can: common questions
What microcontroller does the Stm32-can use?
The Stm32-can is built around the STM32F303CBTx, from the STM32 family.
How big is the Stm32-can PCB?
The Stm32-can measures 33.5 × 63.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Stm32-can?
30 components, from 19 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 Stm32-can design files?
From the acalinp/CANopener repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Stm32-can design in my own project?
Yes, under the terms of its GPL-3.0 license, which acalinp chose for the repository.
Can I test firmware for the Stm32-can 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.
