3.3V 1 Channel Relay Module: Switch Appliances Directly from ESP32 and ESP8266
The DC 3.3V 1 Channel Relay Module lets a low-power microcontroller switch high-power loads like lights, fans, pumps and solenoids. Most relay boards need 5V, but this red board runs on 3.3V, so it fits ESP32, ESP8266 and ESP32-C3 projects without extra level shifting. An onboard transistor driver and LED indicator make it easy to use. A great pick for EEE, CSE and Mechatronics students in Bangladesh building IoT and home automation projects.
Key Features
- 3.3V DC supply and trigger, matches ESP32 / ESP8266 logic

Applications / Project Ideas
- WiFi smart switch with ESP8266 / ESP32
- Blynk and Firebase home automation
- Automatic water pump controller
- Light and fan control by mobile app
- Smart plug and timer projects
- Electromagnet and solenoid lock control
Important Usage Note
This module is for 3.3V only, so do not power it from 5V. Working with 220V AC mains is dangerous: switch off the power, use insulated wires and a proper enclosure, and get help from an experienced person if you are new. Add a flyback diode when switching inductive DC loads like motors.
Package Includes
- 1 x 3.3V 1 Channel Relay Module
