About this item

The 7Semi PT100 RTD Amplifier Breakout Board uses the MAX31865 RTD-to-digital converter to provide precise temperature measurements with PT100 sensors. It supports 2-, 3-, and 4-wire configurations, compensating for lead resistance to ensure high accuracy. Operating at 3.3 V or 5 V, it communicates via SPI for easy interfacing with microcontrollers like Arduino or Raspberry Pi. The onboard Δ-Σ ADC offers 15-bit resolution with 0.03125 °C steps and ±0.5 °C accuracy. It also features built-in over-voltage protection up to ±45 V and comprehensive fault detection, making it ideal for industrial, laboratory, and precision temperature monitoring applications.
