Onboard twelve volt relay

This module features an onboard 12V relay designed to switch larger electrical loads. It provides a safe interface between low-power control circuits and high-power devices.

Manual button control

An onboard physical push-button allows you to manually trigger the relay directly. This is highly convenient for debugging, testing, or standalone manual switching applications.

White connector input

You can also control the relay externally via the integrated white connector. This makes it straightforward to interface with Arduino development boards and other microcontrollers.

Four fixed mounting holes

The PCB is designed with four fixed mounting holes in the corners. This allows you to securely attach the module to your robot chassis, project box, or testing rig.

Safe and environmental design

Manufactured with a sleek black finish, this module adheres to safe and environmentally friendly standards. It is a reliable choice for classrooms, maker spaces, and home electronics labs.
