Looking to use a decent MOSFET with RDS(on) at 4.5V VGS (e.g. IRLB8721) to allow PWM dimming of a strip of 5x Cree XB-D Power LEDs using a 650mA constant current driver.
Are there any modules available with a suitable MOSFET? I see a few using the IRF520 but that isn't a logic level MOSFET, so not really that well suited to the Arduino.
