Introduction
As last-mile logistics evolve, intelligent mailboxes provide a secure and connected way to handle parcel deliveries and pickups. These systems rely on robust, embedded software to manage real-time communication, motorized access, user interfaces, and wireless connectivity. Sigma supported the complete development of embedded software for an IoT-enabled mailbox system, delivering end-to-end functionality across multiple Electronic Control Unit (ECU) applications.
About the Client
The client is a manufacturer of advanced delivery infrastructure, developing intelligent mailbox solutions to support parcel logistics in residential and commercial environments. The challenge was to implement a scalable embedded control system that handles parcel management, connectivity, and user access.
Solution
Sigma’s In-House team served as the dedicated embedded software development team for the project. Scope included:
