PWM (NE555)-based speed controller for up to 20W LED strips or DC motors. Operates on 12V DC. PCB 45 x 33 mm.

• adjustable pulse-width range: 5%...95%
• tested: hardly needs a separate heatsink at 1A load
• workshop tip: if it whines annoyingly, replace the outermost 10nF ceramic capacitor with, for example, a 1nF value

Note! The kit comes preassembled (= FK804).
