Adafruit Square Silicone Button PWM Controller - 3 Wire - 3.6V to 12VDC

This Square Silicone Button PWM Controller offers a satisfyingly squishy feel and is easy to install, providing a versatile PWM output button with three distinct color statuses: red, blue, and green for power adjustments. It's an ideal addition for projects needing a three-cycle power/PWM button and a colorful universal power symbol.

Originally crafted for controlling heating pad modules in wearable thermal vests, its applications can extend to various DIY projects. As a three-cycle button rather than an on-off switch, it ensures multiple power levels with ease.

The integrated LED serves solely as an indicator and works independently from the switch. It requires connection via red and black wires for 3.6~12VDC power input, with blue as the output power wire. Press and hold for two seconds to activate full-strength 100% PWM (red). Subsequent presses reduce to 70% PWM (blue) and 35% PWM (green), offering tailored power control. A long press of two seconds switches the system off.

Best suited for devices like Peltiers, heaters, and fans, this controller’s PWM duty cycle operates effectively where occasional on-off functioning is suitable, providing innovative, functional diversity for tech projects.
