The MCU receives temperature measurements (from an AD7124-4 AFE connected to NTC thermistors) and has the ability to control heating power (via an LTC6992 that PWMs into a buck mode step down voltage converter's MOSFET via a totem pole).
All involved PCBs (apart from the Arduino) are custom designed.
Heaters are made from single side aluminium PCBs with a winding track routing throughout.
The MCU's configuration can be changed, and temperature readings extracted, via a python interface.
The MCU's configuration can be changed, and temperature readings extracted, via a Python interface.
This setup allows the MCU to run a PID loop to stabilize the temperature.
The achieved stability measured in the system is 10 mK.
