MAX31865 Temperature meter module for PT100/PT1000 sensor
MAX31865 has built high resolution ADC converter which is sensitive for noise. The board is designed to eliminate issues caused by noise but some precautions are needed. It is highly recommended to operate the device from stable power supply or battery. Some computers USB supply pins can be noisy, especially if the mains has no proper ground. Some low quality computer power supply can generate noise on USB power pins. If you get permanent errors "PT100 sensor connection fault", I recommended to try it from battery powered device like Notebook computer.
