Description

Just a simple WeMos D1 mini board for led control via WLED app, based on SN74LVC2T45DCUR level shifter.

PLEASE BEWARE !!!

IMPUT VOLTAGE MUST MACH YOUR LED VOLTAGE !

L7805CV Voltage Regulator is there only to provide 5V for the D1 mini.

Please place a jumper into the red 3 pin terminal according to your input voltage (5v or 12v). See the picture below.

There are two versions of PCBs. One with a KF301-2P connector and another one with a power jack connector. Choose the one that fits your needs the most.

Keep in mind that "regular" power jack connectors can't handle to much current so, choose a power jack that can hande your project current draw needs.

For more informations about WLED project, please visit project page : https://kno.wled.ge/, and don't forget to show your appreciation to Aircoookie for his awesome work !

Feel free to improve this design and show us your result ! 🙂
