Although the description says the working voltage is 2.7 - 5.5V, all 5 I got do not work at 3.3V. They start working around 3.9V. This is weird, because already used some identical looking items, and I think I got them from Banggood too, and the old ones work fine with 3.3V. The only visual difference is that the ones I already got have the number "159" on the back, while these are shown as "143". It wasn't a big deal for me, as I simply swapped some of these with the old ones (which were used in 5V circuits), but if you intend to use these with 3.3V, be warned - they might not work.

Module parfait pour un prix très modique. Mise en service très facile, et fonctionnement sans problème avec toutes mes télécommandes. Je recommande sans restriction.

This works as it should. I've uploaded a picture that shows the pinouts.

It just works, use it with my Home-assistant system :D

I am using these receivers mainly as remote controls for heating stove and lights.

I bought these as they are one of the Vishay range of 38KHz IR sensors with built in amplfiers and supression of non-modulated IR sources
