About ESPEED32
ESPEED32 is an open-source slot car controller project built around ESP32 hardware for DIY builders who want flexible setup, tuning, flashing, troubleshooting, and day-to-day racing use.
The project combines controller firmware, a browser-based setup UI, on-device WiFi access, and multilingual documentation so builders and drivers can manage the controller from a laptop, tablet, or phone.
- PWM motor control with adjustable frequency, throttle curve, anti-spin, and brake behavior.
- Magnetic trigger support, calibration, and per-car profile storage.
- Built-in backup and restore, telemetry, firmware updates, storage updates, and an onboard user guide.
Controller Tools and Docs
Open the controller tools page for USB-based access, live tuning, telemetry, backup and restore, and firmware maintenance.
Manage Your Controller Open User GuideHow Access Works
The hosted controller tools page is best for USB/WebSerial access. When you open the controller over WiFi, sensitive tools stay behind controller login and the current password is shown on the device screen.
If you open this page from a local file, the setup UI and bundled user guide still work from the same folder.
Project Resources
The main ESPEED32 repository includes firmware sources, build scripts, hardware context, and the documentation used by both the hosted site and the controller itself.
