BPi-CAN: common questions
What microcontroller does the BPi-CAN use?
The BPi-CAN is built around the PIC16F15325, from the PIC family.
How big is the BPi-CAN PCB?
The BPi-CAN measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BPi-CAN?
146 components, from 89 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 BPi-CAN 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 BPi-CAN 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 BPi-CAN 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.
