The PCBs I designed for a simple LED controller just arrived. They were manufactured by Seeed Studio. The controller has a single FET to set the brightness of a connected LED strip using Pulse-Width Modulation. The PWM signal is generated by a PIC microcontroller and can be adjusted with a single piezo switch.
