Overview

Product Overview

The 1-channel 5V solid state relay module is a compact switching interface that lets Arduino, Raspberry Pi, and ESP32 projects control external devices from a digital pin, making it useful for home automation, robotics, and prototyping. Designed as a low-level trigger SSR board, it activates when the control signal goes low, simplifying integration with common 5V logic setups. The single-channel design is ideal when you need one GPIO-controlled on/off output for smart home builds, test benches, lighting control, and embedded automation tasks without the clicking of a mechanical relay. It is a practical relay module for microcontroller and single-board computer projects where silent solid state switching is preferred for frequent or responsive control.

Questions & answers

Frequently asked questions

Yes, this 1-channel 5V solid state relay module is compatible with Raspberry Pi, allowing control of external devices from a digital pin.
