All in One Railroad Interface: common questions
What microcontroller does the All in One Railroad Interface use?
The All in One Railroad Interface is built around the PIC18F25K80, from the PIC family.
How big is the All in One Railroad Interface PCB?
The All in One Railroad Interface measures 85 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the All in One Railroad Interface?
151 components, from 78 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 All in One Railroad Interface 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 All in One Railroad Interface 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 All in One Railroad Interface 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.
