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
Compré 9 de estas unidades y no puedo conseguir que esto funcione en absoluto, probé diferentes bibliotecas. Pregunte al vendedor por la biblioteca y acaba de decir que no tienen una biblioteca. Sin duda, el vendedor debe ser capaz de dar un enlace a una biblioteca para ESP32. Él debe haber probado esto antes de venderlo!!!!!
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
