Hardware Test Automation Scripting (Board/Box Level)

Problem

Manual device testing and serial communication steps were slow, inconsistent, and error-prone during production validation.

Solution

Built Python scripts using pyserial to interact with devices over serial interfaces, validate responses, and standardize repeatable test flows on Linux; added Bash helpers for station setup and tooling.

Impact

• Reduced manual steps during device testing and improved repeatability across stations.
• Lowered operator error and increased confidence in board/box validation outcomes.

Highlights

• Implemented serial I/O workflows for device bring-up and test execution.
• Standardized scripts to be repeatable across operators and test stations.
