Interface board to easily use an ESP-01 with RGB LED strips. I use this for a TIX clock. Board (and LEDs) powered with 5v DC. A 3.3v regulator powers the ESP-01. I also use a mosfet level converter for the data line, though I don’t know if it’s absolutely necessary… better safe than sorry though.

U1 - TPS732xx (whichever one is 3.3v)
Q1 - BSS138 mosfet
R1,2,4 - 10k
R3 - 300-500 (not critical)
C1 - 10uf
C2 - 0.1uf (I've used 1uf for both and it works)
