The article on Habr describes the development of an Ethernet-RS485 gateway based on the STM32 microcontroller.
The project aims to create a reliable and efficient gateway for centralized control of MySensors nodes in a smart home system.
STM32F103
w5500
The gateway uses the STM32F103CB(8)T6 microcontroller and the W5500 Ethernet chip,
MAX13488
with RS485 communication handled by the MAX13488EESA+T chip.
The article details the design process, including schematic creation, PCB layout, and component selection, and emphasizes the importance of galvanic isolation for reliability. The full article includes schematics, component lists, and explanations of the design choices.
