Scooter Pro

The Scooter Pro combines an electric drivetrain with a digital dashboard, keycards, GPS, and a built-in 4G modem. Librescoot, Sunshine, and stasis put that hardware to use with navigation, trip history, and Bluetooth control.

Model and drivetrain

The Pro shipped from 2021 in 3 kW and 4 kW peak-power variants, both L1e-B with a 45 km/h limit. In Germany, an AM licence is sufficient and is included in class B. The 4 kW version has around 2.7 kW continuous output. The documented 2 kW variant was a 25 km/h test vehicle and was not sold to customers.

Hardware at a glance

• MDB (Middle Driver Board). Main control unit, ARMv7-based, runs Linux. Handles the modem, GPS, NFC, BLE coprocessor, and the interfaces to all other components.
• DBC (Dashboard Computer). Display unit on NXP i.MX6DL with a 480x480 display. With Librescoot, it also displays maps, navigation, and settings menus.
• ECU. Motor controller on the Lingbo platform, with unu-specific Bosch programming. Communicates over CAN bus.
• Batteries. Two swappable main batteries, one additional AUX battery (onboard electrical system, frequently defective) and a CBB (Connectivity Battery, powers the modem on standby).
• SIM. MFF2 (soldered industrial form factor) on the MDB. The original unu SIMs were deactivated. With Sunshine Reconnect, we are planning a way back online without modifying the scooter. Launch depends on how many owners join in.

Current software status

Without any intervention: the scooter rides, the display shows speedometer and battery levels, the steering lock works with a keycard. No longer available: GPS positions, sharing, remote control via the app, and OTA updates from unu. Adding or removing keycards is also off the table: the keycards themselves are stored in the MDB's SAM, but any change requires the card management private key, which was held by unu and is gone with the insolvency.

These projects bring additional features to the scooter:

• Sunshine: browser-based cloud replacement. Available today with a new SIM, for example using the solder-in SIM adapter. Sunshine Reconnect aims to offer a path without hardware changes.
• Librescoot: open-source firmware for MDB and DBC with navigation on the display, alarm system, smart steering lock, and keycard management without a server.

What would you like to use?

• stasis for Bluetooth control from your phone. No new SIM needed.
• Librescoot for navigation, keycards, and a configurable dashboard. Install it using a computer and USB.
• Sunshine for location, trip history, and remote access. You can fit a new SIM today or register your interest in the planned no-modification route at Sunshine Reconnect.

You can combine these projects. See the software overview for features and requirements.
