Scope-X: All-in-One Electronics Learning & DAQ Module

Developed in-house at IIT Palakkad by BumbleBee Instruments Pvt. Ltd., Scope-X is an all-in-one learning and measurement PCB designed for students, hobbyists, and researchers. It integrates the functionality of a 2-channel oscilloscope, function/signal generator, digital I/O interface, and multi-rail DC power supply onto a single compact board with an integrated breadboard for prototyping.

Key Applications & Use Cases

• Op-Amp Experimentation: Circuit analysis and response testing for operational amplifier configurations.
• Frequency Analysis: Fast Fourier Transform (FFT) and frequency response sweeping.
• Digital Logic Testing: Prototyping and testing logic gates, sequential circuits, and digital I/O interactions.
• Home & Lab Prototyping: Powered directly with on-board DC supply rails and built-in breadboard area.
