MCP2515 CAN Bus Module with TJA1050 Transreceiver

The MCP2515 CAN Bus Module is a popular controller interface board used to add CAN (Controller Area Network) communication capability to microcontrollers such as Arduino, ESP32, STM32, PIC, AVR, and Raspberry Pi.

The module uses:

• MCP2515 – A standalone CAN controller that handles message filtering, prioritization, and buffering.
• TJA1050 – A high-speed CAN transceiver that converts the digital CAN signals into the differential CAN bus signals (CANH & CANL).

Together, they allow reliable communication over the CAN protocol, widely used in automotive electronics, industrial automation, robotics, and sensor networks.

This module communicates with the host microcontroller through the SPI interface.

• Support CAN V2.0B technical standard, communication rate 1Mb/S.
