First-boot quickstart
From first power-on to a configured controller. No app to install, no cloud account — everything runs on the controller itself.

Before you start
You'll need the controller wired up:
- Battery to
BAT+andBAT-, run through a fuse and a disconnect switch. There is no reverse-polarity protection — reversing the battery destroys the controller, so confirm voltage and polarity with a multimeter before you connect it. - Motor leads to the
MOTOR OUTPUTterminals. - The
ONpin tied toB-(battery negative) to enable the controller. Leaving it disconnected keeps the controller disabled. - A phone or laptop with Wi-Fi.
The controller runs on 12–85 VDC. The selected battery profile supplies the undervoltage threshold. At the DRV1100BDV5 defaults, sustained overvoltage at 86 V inhibits drive requests and 87 V is critical; dynamic braking and coast follow their existing protection policy. Protection thresholds are not a substitute for an appropriately rated supply. See the fault & LED reference for the full protection table.
1 · Power on
With the ON pin tied to B-, apply power. With no Wi-Fi station connected and no active fault, the status LED is steady. It flashes slowly after a phone or computer joins the controller's Wi-Fi, and flashes quickly while a fault is active. The LED does not indicate that motor output is enabled. If it never lights, check supply wiring, the fuse, the disconnect, and the ON connection. The fault & LED reference explains what each pattern means.
Keep the mechanism secured and verify motor output is off before configuring inputs. Saved direction mappings or Soft Start can already request drive; do not assume that an unfinished wizard prevents motion.
2 · Join the controller's Wi-Fi
On your phone or laptop, open the Wi-Fi list and join the controller's own network:
| Setting | Value |
|---|---|
| Network name | The access point broadcast by the controller |
| Password | SpeedControl |
Your device may warn that this network has no internet access— that's expected. If it offers to switch back to another network, choose to stay connected.
3 · Open the web app
In a browser on the connected device, go to http://192.168.50.1. That loads the controller's web app — every page below is served straight from the controller, so there's nothing to install.
Open Setup Wizardfrom the controller's navigation. The wizard guides the remaining configuration.
4 · Run the Setup Wizard
Keep the motor mechanically secured and make sure the vehicle or machine cannot move unexpectedly. In the web app, select Setup Wizard and follow its on-screen instructions in order.
Work through Direction Control, Tuning Parameters, Brake Settings, Pedal Setup and Battery Profile. Save & Next persists each stage. On Finish, review the Setup Summary before selecting Finish Setup. Finishing returns to Dashboard; motor enable is a separate action. Use Dashboard and Diagnostic to verify inputs, direction, current and faults before physical commissioning. The webapp user manual explains each stage and its dependencies.
Next steps
- Learn what the dashboard's health panel and the status LED are telling you in the fault & LED reference.
- Keep firmware current with the web flasher over the USB-C port. See what's new in each release.
- Something not behaving? The troubleshooting guide is organized by symptom.
Need to restore access? The documented physical boot recovery input enters a dedicated recovery interface with output tasks inhibited; it does not automatically reset saved settings. Follow the board pinout and the recovery reference for explicit paired-upload, password-only and restart actions. Full erase is a separate destructive USB workflow.
