News Summary
- The site controller is built around a Nucleo-H753 featuring the STM32H753ZI microcontroller.
- This site controller board features a dozen output light switches, sixteen front-panel button inputs, dual 24 V PSU inputs, atmospheric pressure and temperature sensors, multiple analog multiplexers, and an ESP32 for internet connectivity.
- There’s also fiber optic TX and RX for talking to the valve controller, a trio of isolated hall-effect current sensors for measuring the generator phase current, through current transformers, four contactor outputs (a contactor is a high-current relay), a line voltage ADC, and the cherry on top — an electronic buzzer.
Over on brushless.zone, weve come across an interesting writeup that details the construction of a dam control system. This is actually the second part, in the first, we learn that some friends pur [+1485 chars]
