Tiny but mighty, the K3 Dual Channel Relay Module is here to take your voltage-switching dreams from theory to execution. Designed to handle two independent 1A channels, this ultra-compact relay weighs in at just 4.5 grams and responds to a 5V control signal—making it the small-but-serious workhorse your project didn't know it needed.
Whether you're automating lights, triggering alarms, or just really enjoy hearing relays click, the K3 gives you both Normally Open (NO) and Normally Closed (NC) control options per channel. Perfect for microcontroller-based systems (Arduino, Raspberry Pi, etc.), and small enough to hide from judgmental eyes.
