CANBuster: common questions
What microcontroller does the CANBuster use?
The CANBuster is built around the PIC18F45K80, from the PIC family.
How big is the CANBuster PCB?
The CANBuster measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the CANBuster?
177 components, from 59 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 CANBuster design files?
From the GBert/misc repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the CANBuster design in my own project?
The repository has no license, so all rights stay with GBert. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the CANBuster without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
