2 Channel 5V Relay Board
10 in stock2-channel 5V relay module with optocoupler isolation and LED indicators for controlling two high-power devices (10A, 250V AC each) with Arduino/Raspberry Pi.
Product Description
The 2 Channel 5V Relay Board is a dual-channel relay module that allows you to control two high-power devices independently using low-power microcontroller signals. Ideal for projects requiring control of multiple devices without the complexity of a 4-channel board. Technical Specifications: - N...
