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; brake, regeneration, 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.
Even with the output enabled, the motor won't turn until you set a direction (step 4), so nothing moves yet.
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.
On Setup Summary, verify every value before selecting Confirm Setup. Choose Enable Motor Now only after the wiring and direction are verified and the area is safe; otherwise choose Enable Later. Use Dashboard and Diagnostic afterward to confirm live inputs, direction, current, and fault status.
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.

Need to restore access? Connect the
RSTpin to 3.3 V while the controller boots. RST restores the default Wi-Fi credentials (PW-AP-1/SpeedControl), developer settings, primary board role, and extension default. It preserves motor, battery, direction, and protection configuration. Use the USB full-erase workflow only when a complete reinstall is required.
