Experimental instrumentation is essential in physics laboratory education; however, access to flexible and affordable systems remains limited, particularly at the secondary and undergraduate levels. This paper presents the development of a low-cost programmable instrumentation platform designed specifically for physics laboratory education. The platform adopts a system-level architecture that integrates data acquisition, control, and communication within a unified hardware framework while maintaining simplicity and low cost. Functional versatility is achieved through software-defined operating modes, allowing the same hardware platform to support multiple physics experiments without hardware modification. The performance of the platform is validated using representative laboratory experiments, including manual time measurement, linear motion analysis using photogate sensors, and DC voltage measurement. Hardware-level signal conditioning is complemented by basic firmware-based data processing to improve measurement stability and usability, while quantitative accuracy is established through calibration against reference instruments. Experimental results demonstrate stable operation and strong agreement with standard laboratory instruments within the intended educational operating ranges. The proposed platform provides a flexible, transparent, and cost-effective alternative to commercial laboratory equipment. Its programmable nature supports hands-on learning, experiment customization, and active student engagement, making it particularly suitable for physics education in resource-limited secondary and undergraduate laboratory environments.
