Indicator with output signal The signal input port can be connected to the IO port of the single chip microcomputer, and the high-level signal is driven Dual power supply selection design has strong anti-interference ability and high reliability of photoelectric isolation protection Onboard 3V,10A/250VAC; 10A/30V DC relay, which can be continuously closed for 100,000 times, with diode laxative protection, short response time The external connection adopts rotary crimping terminal to make the connection firmer, With fixed mounting holes for easy installation The 3V relay isolation drive control module, the core is the electronic control device relay, which has a control system (also known as the input loop) and a controlled system (also known as the output loop). The essence is an automatic switch that uses a smaller current to control a larger current ". Used to control 10A 250VAC and 10A 30VDC loads, with output signal indicator prompts. Dual power supply selection design is adopted to enhance anti-interference ability. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

Review: Good for 3v io systems like raspberry pi pico - Wish Id bought the 10 pack. Worked as described, triggered by a raspberry pi pico gpio and a separate 3.5v power supply for the relay module Vcc.
Review: 3.3v works great with D1 Mini - Used for a project with ESP8266 D1 Mini. Works great with 3.3v trigger

### ⭐⭐⭐⭐⭐ 3.3v works great with D1 Mini
*by D***Y on April 12, 2026*

Used for a project with ESP8266 D1 Mini. Works great with 3.3v trigger

### ⭐⭐⭐⭐ Here's a schematic and photo
*by F***S on February 26, 2026*

Here's the KiCad schematic I made. It's a nice little board, works great driven from my 8266 ESP-12E dev board output pin, and using the 3.3v output pin for the VCC input. The vendor really should have supplied a schematic for folks!
