This PCB is outdated and I can no longer recommend using it. Please use WLED-PCB-V2 instead. It has much more safety features.
This is a PCB to control a 12V GS8208 LED Stripe with WLED. The PCB contains a voltage regulator to provide 5V for the Wemos D1 mini and a level shifter for the signal line. Furthermore, the PCB is designed so that it goes directly inbetween the power supply and the LED Stripe.
This project is for an external ambilight solution for a VESA mounted monitor. Therefore the width of the PCB is given by the L-profile where the PCB is mounted on.
This PCB was designed in KiCad.
