Colibri PID is an expansion module with one Pt1000 temperature sensor input and one Analog 0-10 volt output, and an on-board STM32F030 that implements a PID regulator.
MAX31865 is the resistor Whetstone bridge A/D converter. It uses SPI as the interface.
MCP4725 is the 12 bit D/A converter used.
I2C Addresses
24LC16 = 0x50-0x57 STM32F030 = 0x10-0x1F
MCP4725 = 0x60 ; This is on a separate I2C bus, connected only to the on-board STM32F030
