Note: A PT100 sensor is required for use. Any three or four wire PT100 sensor will work. While we

don't currently carry a PT100 sensor, we plan to carry one in the near future.

that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm

pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized

connections mean you can’t hook it up wrong.
