Built and Backed by Compoden
Every part you buy from Compoden comes with an AI build companion — delivered via QR, email, or WhatsApp — that helps you wire and program this switch into a working project. With 10 years of experience supplying makers and institutions across India, we ensure you get reliable components and real support. Pay your way: UPI, cards, or Cash on Delivery, anywhere in India.
How do I wire this switch to a 5V fan?
Connect the fan’s positive wire to the switch’s output positive, and the fan’s negative to the switch’s output negative. Then connect the switch’s input to your 5V power source. The PWM signal wire goes to a GPIO pin on your controller (e.g., Raspberry Pi or Arduino).
