Payment for the executive device according to the RS-485 Modbus protocol

Prototype STM32 (SOP20) control module designed for receiving commands and sending status (information, temperature) to the central control console. A DC-DC converter up to 40 volts is used for power supply, with an RJ-45 connector, and the Modbus protocol provides half-duplex communication (request-response) in this case with 6 registers for data transmission. Compact dimensions for placement in a 220-volt socket (socket box).
