Overview

Product Overview

MCP2515 CAN Bus Module is a SPI CAN interface that adds Controller Area Network communication to microcontroller projects using the MCP2515 CAN controller and TJA1050 transceiver. It lets Arduino, Raspberry Pi, ESP32, and other SPI-capable boards send, receive, and monitor CAN bus data for automotive diagnostics, industrial control, robotics, and embedded prototyping. Use it to connect sensors, ECUs, motor controllers, or distributed devices over CAN when your host board does not have native CAN support. It is also useful for CAN bus sniffing, custom dashboards, battery management systems, and networked nodes that need reliable message exchange through a standard SPI connection. The header pins ship pre-soldered, so it works out of the box with no soldering required.

Questions & answers

Frequently asked questions

It works with Arduino, Raspberry Pi, ESP32, and other SPI-capable host boards when supported by compatible software or drivers. The module adds CAN communication through the MCP2515 controller and TJA1050 transceiver.
ShillehTek supplies this module with pre-soldered headers, so header soldering is not required before breadboard or jumper-wire use. You still need to wire SPI, CANH/CANL, power, and ground, then configure host software.
It uses SPI between the host board and MCP2515 CAN controller, plus a TJA1050 transceiver for the physical CAN bus. Typical connections include SCK, MOSI, MISO, chip select, interrupt, power, ground, CANH, and CANL.
Yes. It can send, receive, and monitor CAN frames, making it useful for automotive diagnostics, CAN sniffing, custom dashboards, and ECU-related prototyping. The host software must match the bus bitrate and interpret the message data.
Check CANH/CANL orientation, shared ground, matching CAN bitrate, correct SPI chip-select and interrupt settings, and proper bus termination. Also confirm the CAN network is active; the module will not show frames on a silent bus.
