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. Colibri pid-RevA-front3d.png Colibri pid-RevA-back3d.png

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, 0x61    ; This is on a separate I2C bus, connected only to the on-board STM32F030
