Python & CircuitPython

It's easy to use the MAX31865 sensor with Python or CircuitPython, and the Adafruit CircuitPython

MAX31865 (https://adafru.it/Cbp) module. This module allows you to easily write Python code that reads the

range from the sensor.

You can use this sensor with any CircuitPython microcontroller board or with a computer that has GPIO and Python

thanks to Adafruit_Blinka, our CircuitPython-for-Python compatibility library (https://adafru.it/BSN).

CircuitPython Microcontroller Wiring

First wire up a MAX31865 to your board exactly as shown on the previous pages for Arduino. Here's an example of

wiring a Feather M0 to the sensor with a SPI connection:

Board 3V to sensor VIN

Board GND to sensor GND

Board SCK to sensor CLK

Board MOSI to sensor SDI

Board MISO to sensor SDO

Board D5 to sensor CS (or any other digital I/O

pin)

Python Computer Wiring

Since there's

dozens

of Linux computers/boards you can use we will show wiring for Raspberry Pi. For other platforms,

please visit the guide for CircuitPython on Linux to see whether your platform is supported (https://adafru.it/BSN).

Here's the Raspberry Pi wired with SPI:

Pi 3V3 to sensor VIN

Pi GND to sensor GND

Pi MOSI to sensor SDI

Pi MISO to sensor SDO

Pi SCLK to sensor CLK

Pi GPIO5 to sensor CS (or use any other free GPIO

pin)
