Lyft SIT032B Scooter Interface Module User Manual
Introduction
Module Summary
The Lyft SIT032B module provides wireless connectivity, location, and card
reader functionality for the Lyft SCT-03-0-x shared e-scooter.
The module communicates with the controllers inside of the scooter to control
motor speed, braking, and lighting; and to report the status of the scooter to
an internet application over LTE.
This module is only intended to be used by Lyft for integration into their own
products, and will not be sold to other companies or to consumers.
This module should not be used in any other circumstances
External Interfaces
The module exposes five external cables that connect to the shared scooter
hardware.
These connectors are the following:
- Connector 1 (5 pins): Julet JL-F39-Z508JG Male
- Connector 2 (4 pins): Higo Z409BMP Male
- Connector 3 (2 pins): JST ZMR-02
- Connector 4 (3 pins): JST ZMR-03
- Connector 5 (3 pins): JST ZHR-03
Installation Instructions
The Module must only be installed on a host as approved by Lyft in the
SCT-03-0-x manufacturing SOP in order to ensure compliance with applicable FCC
regulations.
A brief summary of the key electrical and mechanical connections is included
below for reference.
Electrical Connections
The connectors on the module must be attached in this order:
- Connector 2 (optional)
- Connector 3
- Connector 4
- Connector 5
- Connector 1
Caution should be observed when plugging in Connector 1, as this applies power
to the system.
To prevent damage during bring-up, the Connector 1 power should be disabled
while inserting the connector.
Mechanical Connections
The Module must be mechanically joined to the shared scooter to ensure that
the signal and power connectors are securely mated during motion.
Screw threads are provided within the device’s housing for secure attachment
to the shared scooter base.
The mechanical mount has been designed to mate with a Lyft-designed custom,
plastic plate that is affixed to the SCT-03- 0-x handlebar area.
The Module must be mounted by following the Lyft-approved manufacturing SOP in
order to ensure that the user is more than 70mm away from all radiating
elements.
In addition, the Module must only be mounted to a stem that shares the same stem and handlebar geometry as the SCT-03-0-x in order to ensure that the NFC antenna is isolated from the metal in the scooter handlebar and stem.
