This repository contains firmware to drive a 36V Electronic Speed Controller (ESC) for a DC motor. This project has been tested to handle a 3A load without issue. Motor speed is monitored and controlled using a hall effect sensor and PID feedback.
Driver code for the H-Bridge circuit is found in /Core/Src. The files main.c, H_bridge.c, user_input.c and rpm_feedback.c contain custom code developed for this project.
Images of the project are found below, along with an operation guide.
Load Testing
Operation Guide
- Construct circuit shown in the latest schematic version with the parts listed in the expense report.
- Optional: Order two PCBs using the files in /H_Bridge_KiCAD and /STM32_KiCAD.
- Program STM32 chip with the code, found in this repository, using SWD.
- Power on circuit and controller.
- For safety, the device starts in an OFF state. Shift the direction switch once to begin operation.
- Use the potentiometer to set a desired speed within the range of 60 to 200 RPM.

Questions
How big is the H Bridge KiCAD PCB?
It measures 159.5 × 62.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the H Bridge KiCAD use?
44 parts, built around the IR2011PBF, IRF530N-VB and MBRF10200. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the H Bridge KiCAD KiCad files?
From the JoshWilbur/Electronic-Speed-Controller repository on GitHub, at the commit this page was made from: the board is H_Bridge_KiCAD/H_Bridge_KiCAD.kicad_pcb and its schematic H_Bridge_KiCAD/H_Bridge_KiCAD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the H Bridge KiCAD design in my own project?
Its repository states no licence, so its author keeps all rights: ask JoshWilbur before reusing the design.
