SpletThe FQP30N06L MOSFET (datasheet) is an N-channel MOSFET designed for switching high-speed circuits, and it’s perfect for switching LEDs. It can control up to a 60V, 30A load and can be switched from 3.3V or 5V. Figure 3. MKR Zero connected to a FQP30N06L MOSFET for controlling an LED lamp. Figure 4. SpletTurning LEDs on and off manually is as simple as it can get: Just put a switch in series with the LEDs you want to control. Most buttons and small switches will handle 100mA or so. More rugged switches, such as those used in power supplies, will handle a few amps. reach brickell
