TJA1050 CAN Controller Bus Driver Interface Module

TJA1050 CAN Controller Bus Driver Interface Module 

The TJA1050 CAN Bus Driver Module is a high-speed CAN transceiver designed to interface between a microcontroller’s CAN controller (TX/RX signals) and the CAN bus differential lines (CANH, CANL).
It converts the logic-level CAN signals into differential signals suitable for robust, long-distance communication used in automotive and industrial systems.

This module is commonly paired with CAN controllers like MCP2515, STM32 built-in CAN, or Arduino Due CAN.
It provides reliable, noise-immune communication and supports speeds up to 1 Mbps.
