# DevLab: G6K-2G-Y-TR 5V Relay Module

This dual-channel relay module is engineered to safely and reliably interface with microcontrollers that manage higher-voltage or higher-current loads. It provides a dedicated 5 V supply for powering the relay coils while the logic supply is aligned with the microcontroller’s I/O voltage (3.3 V or 5 V). The module accepts digital control signals to toggle the relays, and the relay contacts are designed with both normally-open (NO) and normally-closed (NC) configurations, offering versatile switching options.
