RelayTrackerController: common questions
What microcontroller does the RelayTrackerController use?
The RelayTrackerController is built around the ATmega328-A, from the AVR/Arduino family.
How big is the RelayTrackerController PCB?
The RelayTrackerController measures 54 × 94.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the RelayTrackerController?
86 components, from 41 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 RelayTrackerController design files?
From the bask185/Train-Science-DIY repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the RelayTrackerController design in my own project?
The repository has no license, so all rights stay with bask185. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the RelayTrackerController without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
