Train Driver Hardware

Hardware design files for the Train Driver project.

Overview

This repository currently contains the KiCad project and schematic for a simple MCU-based circuit intended to drive two PWM-controlled trains.

A STM32F103C8T6 Blue Pill is used as the main controller, reading two potentiometers and then running two FET drivers via PWM.

A snippet of the transister driver circuit is shown below:

A full bridge rectifier is also used, to which a snippet is also shown below:

Falstad Simulation

Falstad was also used to simulate parts of the circuit, the simulations can be found in .txt format in the simulations folder.

We can see the circuits below:

PWM Channel Simulation

Bill of Materials

The Bill of Materials can be found in the GitHub releases, which is created automatically by the Kicad GitHub Actions workflow.
