This week we got a request on the forums (https://forums.adafruit.com/viewtopic.php?t=219635) for a way to read PT100/PT1000 RTD sensors over I2C. To be honest, we only really stock the MAX31865 (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/MAX31865ATP/3681476) which is SPI only. Let's find a chip that could do RTD reads over I2C: that would require 24-bit precision, but not necessarily high speed! Also ideally it could do differential reads. See the chosen part on DigiKey https://www.digikey.com/short/q7z2575h #circuitpython #sensorhacks #thegreatsearch
