Review on 🔌 XCSOURCE 5PCS IIC I2C Logic Level Converter Bi-Directional Module: Efficient 5V to 3.3V Conversion TE291 by Kenneth Barnes

I installed 3 out of 5 logic converters, 2 didn't work. Upon further investigation, I noticed that one of the dual-chip surface mount components was not properly attached. I checked that with a microscope. I emailed the seller to see if I could replace these two chips. Otherwise the other 3 chips worked as expected and the chips actually matched the picture. Upgrade to two stars. Updated: 05/09/2020. I'll try again with my return. All 5 worked as expected with no issues, I upgraded to 4 stars, the supplier was responsive and honest. I will buy from these people again!
