Selection reference · illustrative scenario
Clock roles in the application
Roadside equipment, logistics trackers and in-vehicle devices have different environments and documentation needs. Identify the project and component role first.
Engineering selection review
Review communication references, positioning inputs, event time and data interfaces. Confirm any automotive grade, temperature or reliability documents by full part number rather than by application category.
Procurement and documentation
Include roadside/tracking/in-vehicle use and positioning and communication chips, plus the existing full code, sample and production quantities and delivery target. Discuss nominated international brands and domestic candidates separately, confirming parameters and documents by part.
Illustrative validation scenario
Plan start-up, power-loss, temperature and link tests for the installation and system requirements, limiting approval to tested conditions.
