Unlock the Power of Automation with the Ultra-Compact 1-Channel 3V-5V Relay Module!
Whether you are a hobbyist working on Arduino, ESP32 or Raspberry Pi projects, a student learning electronics, or a developer prototyping smart home automation, this relay module is the perfect bridge between low-voltage microcontrollers and high-voltage/high-current appliances. It acts as an automatic switch that utilizes a small electric current to control a much larger one safely and efficiently.
Key Features & Technical Specifications:
Operating & Input Voltage: Fully supports 3V to 5V logic/input systems, highly adaptable for 3.3V and 5V MCUs.
Premium Relay Core: Equipped with authentic TONGLING JQC-3FF-S-Z relay rated for 10A 250VAC / 15A 125VAC / 10A 30VDC.
Anti-Reverse GVS Interface: Clearly labeled 3-Pin interface: V (VCC Power), G (GND Ground), and S (Signal Input).
Trigger Logic: High-Level Trigger. When Signal (S) is HIGH, Relay closes (NO connected to COM). When Signal (S) is LOW, Relay opens (NC connected to COM).
Dimensions: Pocket-sized 38.4mm x 22.4mm x 13mm (1.5" x 0.9" x 0.5") with pre-drilled positioning holes for stable mechanical mounting.
Value-Added Package:
No more hunting for the right connector cables! We include a custom PH2.0 to DuPont wire in the package, allowing you to instantly hook the module up to breadboards, development boards, or sensor shields right out of the box.
Package Includes:
4 x 1-Channel Relay Module (High Level Trigger)
4 x PH2.0 to DuPont Connecting Cable
