This study presents a fully digitalized control system for quantum optics experiments implemented on a Teensy 4.1 microcontroller.DDS signal generation and synchronous detection were completed on the microcontroller, and high resolution and wide-range environmental drift tracking were achieved through cooperative control of two DAC systems with different weighting in the post-DAC stage. Automatic relocking was also achieved through DC signal monitoring, and a centralized monitoring system for multiple units was constructed via Python. It was implemented in a stabilization experiment for MCC and SHG resonators, and long-term stable operation was confirmed.
