HITL SAM Board Tester — Hardware-In-The-Loop Avionics Validation System
An active Hardware-In-The-Loop test system for validating YJSP rocket avionics in a controlled lab environment, targeting a fully-automatic CI/CD pipeline. The first project under the HITL program: SAM Board Tester — emulating sensors, actuators, and power interfaces for FSAM/GSAM validation.
Multi-Channel USB to CAN / UART Converter — RoboMaster Control Interface
A compact 5×5 cm USB hub board providing 4× CAN and 3× UART channels for a Linux-based RoboMaster robot, featuring deterministic port-number sequencing via hardware power-up timing control.
