This Controller
Technical details for the physical controller you are connected to.
---------------Telemetry & Logging
Live logging works over controller WiFi or USB WebSerial, with local CSV/JSON export. Time runs left-to-right in seconds since session start.
Lap Overlay
Analyze exported telemetry JSON or the current telemetry buffer. Finds laps from the longest high-throttle straight and overlays each lap by lap progress.
Config Backup & Restore (.json)
Download Backup
Create a JSON snapshot of current settings and car profiles.
Restore Backup
Upload a previously exported JSON backup to restore configuration.
Advanced Config Editor
Works over WiFi and USB (after Connect via USB).
Automatic Update Firmware and File System
Release pair to install.
Do not disconnect power during update.
Manual Update Firmware and File System
Select both files from the same release. The controller uploads firmware first and filesystem second, then reboots once at the end.
Use this if you already downloaded a matched firmware + SPIFFS pair, including sensor-specific firmware builds such as AS5600.
Do not disconnect power during update.
Advanced — Upload Single Component
Only use this if a paired update partially failed and the controller has not rebooted yet. Uploading a single component leaves firmware and filesystem out of sync until both are updated.
Do not disconnect power during update.
