Product Description
Enable high-speed industrial communication in your projects with the MCP2515 CAN Bus Module. This module acts as a bridge between your microcontroller's SPI port and the Controller Area Network (CAN) bus, which is the standard for automotive and industrial data transmission. At Robogears, we recommend this module for building OBD-II scanners, vehicle telemetry systems, and long-distance sensor networks. It combines the MCP2515 standalone CAN controller with the TJA1050 high-speed transceiver, providing a complete physical and data-link layer solution. Whether you are hacking your car's dashboard or networking multiple robots at your Pimpri workshop, this 5V module ensures robust, error-resistant data transfer over long cable lengths.
Detailed Key Features
Full CAN V2.0B Support: Capable of transmitting and receiving both standard (11-bit) and extended (29-bit) data frames at speeds up to 1 Mb/s.
SPI Interface: Uses standard SPI pins (MOSI, MISO, SCK, CS), allowing it to be easily interfaced with Arduino Uno, Mega, Nano, and STM32.
Hardware Filters & Masks: Features two receive buffers with three mask registers and six filter registers to offload message filtering from your main CPU.
TJA1050 Transceiver: Provides the physical interface to the bus with high electromagnetic immunity (EMI) and low electromagnetic emission (EME).
On-board Termination: Includes a 120-ohm termination resistor (usually enabled via a jumper) to prevent signal reflections on long bus lines.
