This PCB is designed for a MAX6675 and I am sure it will work fine with this chip. The unit selling at this offer is equipped with the better MAX31855 and was only able to work after some small modifications: According to the datasheet no connection is allowed between T- and GND as the MAX6675 needs this link. So I was not able to get this thing working until I cut the trace between pin 1 and 2. After that I got readings from my thermocouple but there were not correct. After adding a capacitor (47 or 100nF) between T+ an T- it works flawlessly.
Great product!!
Received it in two weeks. Will test it soon
J'ai acheté 9 de ces unités et je ne peux pas obtenir que cela fonctionne du tout, essayé différentes bibliothèques. Demandez au vendeur pour la bibliothèque et il dit juste ne pas avoir une bibliothèque. Sûrement le vendeur doit être en mesure de donner un lien vers une bibliothèque pour ESP32. Il a dû le tester avant de le vendre!!!!!
Convenient interface modules for easy hook-up of thermocouple sensors. Good price, great deal.
Perfect!
chegou tudo certo.
parfait
as expected
Not tested yet but, apparently, all is ok
