Autostop Detector: common questions

What microcontroller does the Autostop Detector use?

The Autostop Detector is built around the SN65HVD230, from the ESP32 family.

How big is the Autostop Detector PCB?

The Autostop Detector measures 52 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Autostop Detector?

13 components, from 11 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 Autostop Detector design files?

From the Monash-Railway-Express/KiCad_Files 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 Autostop Detector design in my own project?

The repository has no license, so all rights stay with Monash-Railway-Express. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Autostop Detector without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
