Product Description
Product Description
The Waveshare RS485 Board (3.3V) is a serial interface converter module for RS485 communication with 3.3 V logic levels. It integrates an SP3485 transceiver and is intended to connect microcontroller or embedded UART interfaces to an RS485 bus.
The board provides a compact communication interface for industrial and general serial data transmission tasks. Its 3.3 V operating voltage makes it suitable for systems that use non-5 V UART logic. Based on the available source data, no USB, RS232, or simultaneous multi-output capability is indicated; the module is conservatively described as a TTL-UART to RS485 conversion board.
Technical Features
- Serial interface converter module for TTL-UART to RS485 conversion
- Onboard transceiver: SP3485
- Operating voltage: 3.3 V
- Designed for RS485 communication
- Suitable for 3.3 V logic systems
- Compact board format for embedded and microcontroller applications
Application Areas
Typical applications include connecting microcontrollers, single-board computers, and embedded controllers to RS485 networks. The board can be used in prototypes, test setups, serial control links, and general communication applications where UART signals must be converted to a differential RS485 interface.
It is also suitable for laboratory setups, industrial communication evaluation, and interfacing external RS485 devices with 3.3 V control electronics. Because the provided source material is limited, additional electrical limits and connector details should be verified against the manufacturer documentation before integration.
