The system combines a Raspberry Pi 5 host for multi-stream ingestion, visualization, and storage with an Arduino UNO R4 WiFi microcontroller dedicated to sensor acquisition. The electronics integrate commercial off-the-shelf (COTS) modules through an engineered interface layer including protected power distribution, logic-level adaptation, and a DB-37 expansion connector exposing I2C-SPI-ADC lines for external instrumentation. On the telemetry side, the microcontroller firmware performs automatic I2C discovery, conditional sensor handling, and outputs framed NMEA-like messages with XOR checksum and explicit block delimiters, enabling robust parsing and synchronization on the host. A finite-state control (STOP-RUN-SIM-INIT) and watchdog-style recovery actions implement resilience under partial hardware availability and field failures. The host software adopts a multi-process architecture with independent readers for event, telemetry, and actuator streams, message queues for isolation, and coherent time-stamped logging across streams. A simulation mode and integrated command channel allow end-to-end pipeline verification and rapid commissioning without full sensor availability. The paper details architecture, electronics integration, firmware protocol, host software design, and functional/engineering validation procedures, providing a reproducible blueprint for portable instrumentation readout and contextual telemetry acquisition.</summary>\n    <category scheme='http://arxiv.org/schemas/atom' term='physics.ins-det'/>\n    <published>2026-03-16T07:04:30Z</published>\n    <arxiv:primary_category term='physics.ins-det'/>\n    <author>\n      <name>D.
