Two-controller STM32 + STM8 control module

Completed two-controller STM32 + STM8 (SOP20) control module designed for receiving commands and sending status (information, temperature) to the central control console. The actuator device is a bistable relay. The second controller (STM8) is a backup, servicing the system in standalone mode (or in emergency mode, in case of communication loss). Pulse DC-DC, connection via RJ-45 connector, Modbus protocol provides half-duplex communication (request-response). Compact size for placement in a 220-volt socket (socket box). Developed and programmed, as well as manufactured the printed circuit board (full cycle) in our laboratory.
