CABUREI
Overview
The Caburei mission is an Automatic Packet Reporting System (APRS) payload designed to support communication through the amateur radio community. It operates in both store-and-forward and digipeating modes, allowing packets to be received, temporarily stored, and retransmitted to extend communication range.
Design
The Caburei mission PCB is designed around a compact and modular architecture, integrating a Raspberry Pi Zero 2W as the primary processing unit. The board includes a 50-pin connector for interfacing with the satellite bus, along with a 3.3V LDO regulator for stable power delivery.
Overcurrent protection (OCP) circuits are implemented across key subsystems, including dedicated protection for the transceiver and the onboard processor. The design also incorporates a WM8960 audio codec for signal processing and an SMA antenna interface for RF connectivity.
Objectives
The mission aims to enhance communication capabilities for the amateur radio community while also serving as an educational platform for students learning wireless communication using low-cost hardware. In addition, it provides a resilient APRS-based backup communication link, supporting operators in remote and disaster-affected areas.
