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.

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.
