This power supply latch provides power to the external circuit you wish to power, allowing it to remain powered on or turn off after completing its operations. It functions like a self-holding relay but is solid-state and is suitable for handling a wide range of DC voltages from 5 to 30 volts. It is ideal for powering devices and electronic circuits, particularly logical ones, that can remain on for the required time once activated.

Compatible with Arduino, this latch is perfect for DIY projects and automation applications. Thanks to this compatibility, it can be easily integrated into your Arduino-controlled electronic projects.

This type of circuit is very useful because it allows you to turn the power of a device on or off with a simple press of a button and consumes very little energy when in a resting state.

The product comes with usage instructions in Italian and does not include pin strips, which can be purchased separately.

The power supply latch can be used to power on an Arduino board, which can manage various types of circuits. The provided example sketch (available at the bottom of the page) is designed to set a Digital Output to a high level when it receives power and let it return to zero once it has completed its task, such as when an event like data acquisition from a sensor and sending it over a serial port or wireless interface has occurred.

Please note: The Arduino board is not included and must be purchased separately.
