The MCP2515 CAN Bus Module adds CAN 2.0B communication capability to microcontrollers that do not have an integrated CAN controller. It combines the Microchip MCP2515 stand-alone CAN controller with a TJA1050 high-speed CAN transceiver, providing a convenient SPI-to-CAN interface for Arduino, Raspberry Pi, STM32, AVR, and other microcontroller projects.

The module supports standard 11-bit and extended 29-bit CAN frames, with communication speeds of up to 1 Mbps. An onboard 8MHz crystal oscillator and 120Ω termination resistor make it convenient for CAN bus prototyping, automotive diagnostics, industrial automation, and embedded CAN networks.
