Boards are not rated for 5v even though they have 3-5v written all over them. Voltage regulator gets smoldering hot at 5v and then the chip is dead. Fried the first 2 by connect VIN to 5v and 0v to GND. Third one I tried at 3.3V and while it didn't get burning hot it also still didn't work. Chinese clone of an actual adafruit chip that doesn't work.

To use with the reference code for the Adafruit Arduino library and a 3-wire RTD, you need to cut the jumper trace on the "24 3" pads. The default configuration is for 2/4 wire RTD's, and this will cause the sensor to read off by a few hundred degrees. Cutting the trace and putting a solder blob over the center and 3 pads corrects it if you're using a 3-wire RTD.There is an additional solder pad to jumper underneath the negative side, "labelled 2/3 wire".In summary:4 wire RTD: no soldering3 wire RTD: jumper the 2/3 wire pad below the negative terminals, cut the trace on the "2/4 3" pads above the reference resistor, and jumper between center and "3".2 wire RTD: jumper the 2/3 wire pad below the negative, jumper the 2 wire pad below the positive, leave the "2/4 3" pads alone.

Doesn't seem to work right with 3 wire RTD
