Product Overview

The 5-Pin Relay Breadboard Adapter from Pro Tronix solves a common headache for students and makers. Standard 10A power relays (like the SRD-05VDC-SL-C) have pin layouts that do not align with the standard grid of a breadboard, often leading to bent pins or loose connections.

This adapter base features a top-side socket that fits your relay perfectly and a bottom-side pin header that snaps securely into any standard breadboard. It transforms a bulky power component into a breadboard-friendly module, making it easier than ever to test your Arduino or ESP32 control circuits before moving to a permanent PCB.

Technical Specifications

Key Features

• Instant Prototyping: No more soldering wires to relay pins just to test a circuit on a breadboard.

• Rock-Solid Stability: Designed to sit flat on the breadboard, preventing the relay from wobbling or disconnecting during testing.

• Standard 2.54mm Pitch: Fully compatible with all MB-102 breadboards and jumper wires.

• High-Current Path: Engineered with wide PCB traces to handle the current needs of the relay coil and contacts during prototyping.

Common Applications

• Classroom & STEM Labs: Teaching students how relays work without the risks and mess of soldering.

• Rapid IoT Prototyping: Testing smart home logic with ESP32 or Raspberry Pi before finalizing the hardware design.

• Project Debugging: Easily swapping between different relay voltages (e.g., switching from 5V to 12V) during the development phase.

• Temporary Test Jigs: Building quick setups to verify the functionality of sensors and actuators.
