Customer:
Does the Logic Converter work bidirectionally, or does it only convert 5V to 3.3V or vice versa?

Soldered Support:
This board converts signals up to 5V into signals up to 3.3V, and does not function in the reverse direction.
Sending a 3.3V signal into a 5V circuit will technically work without conversion, but could cause unpredictable behavior. 5V logic circuits typically interpret a logic high at around 2.7V and above. I don’t officially recommend this, but it may work well enough for simpler projects.
Original message (Croatian)
ova pločica pretvara signal koji ide do 5V u signal do 3V3, i ne funkcionira obratno.
Slanje 3V3 signala u krug od 5V se bez pretvaranja tehnički smije raditi, ali bi moglo uzrokovati nepredviđeno ponašanje. 5V strujni krugovi inače interpretiraju logičku jedinicu oko 2.7V nadalje. Ne preporučujem ovo službeno, ali bi moglo raditi dovoljno dobro za potrebe nekog jednostavnijeg projekta.
