RS485, RS232 & CAN Interfaces for Arduino, ESP32 & Electronics Projects

RS485, RS232 and CAN modules are commonly used when a project needs reliable wired communication between devices. They are used in sensor networks, data logging, automation prototypes, serial device interfaces, long cable runs, embedded systems, robotics and control projects.

Many modules connect to a microcontroller using UART, SPI or TTL-level signals depending on the interface type. Always check the supply voltage, logic level, communication protocol, wiring method, termination requirements, driver library support and pinout before ordering.

RS485 vs RS232 vs CAN Bus

RS485 is commonly used for longer-distance serial communication and multi-device networks. RS232 is an older serial communication standard often used with legacy equipment and serial devices. CAN bus is a robust communication bus commonly used in automotive, machinery, embedded control and multi-node electronics projects.
