CJMCU-1051 TJA1051 CAN Transceiver Module - High-Speed, Low Power Previous 
The SP3485 RS485 to TTL Module is a breakout board for RS-485 serial conversion. It converts a UART serial stream to RS-485 communication and uses the SP3485 RS-485 transceiver IC. The module operates from a single +3.3V supply and supports +5.0V logic. It is a half-duplex transceiver, so communication works in one direction at a time. The board provides multiple connector options for RS-485 input and output.
