Control High Voltage Devices with Relay Modules
Relay Modules are essential for switching high voltage appliances using microcontrollers like Arduino, Raspberry Pi, or ESP boards. Available in 1-channel, 2-channel, 4-channel, and 8-channel variants, these modules allow safe interfacing of AC loads with low-voltage digital control systems.
Ideal for automation, home control, IoT, and robotics projects, Stemvolt offers tested and high-quality relay boards to ensure secure and reliable operations in your DIY and industrial-grade builds.
