Elecrow CAN-Bus Shield V1.5 for Arduino Uno – MCP2515 & MCP2551
Elecrow CAN-Bus Shield V1.5 for Arduino Uno – MCP2515 & MCP2551
The Elecrow CAN-Bus Shield V1.5 equips your Arduino Uno with full CAN bus communication capabilities. Built around the MCP2515 controller and MCP2551 transceiver, it supports CAN V2.0B at speeds up to 1 Mb/s. An onboard microSD card slot allows data logging, while the screw terminal provides secure CAN bus connections.

Compatibility
Designed for direct stacking on Arduino Uno, using SPI pins D10–D13 and the ICSP header. It can also work with Arduino Mega by adjusting the CS pin in software, though physical stacking requires jumpers. Works with 5V logic boards only; not directly compatible with 3.3V systems.
Wiring Notes
Simply stack the shield on your Arduino Uno and connect CAN_H and CAN_L to the screw terminal. If your CAN network requires termination, add a 120Ω resistor across the bus lines. The microSD slot uses SPI chip select D4 by default; ensure no conflicts in your sketch.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Mega?
The shield is designed for Uno pin headers but can communicate with a Mega via jumper wires. Connect SPI pins (MISO, MOSI, SCK) to the Mega's dedicated SPI header, and assign digital 10 as the chip select in your code.
Does it include a microSD card?
No, the microSD card is not included. You'll need to supply your own FAT16/FAT32 formatted card, up to 32 GB in capacity.
What libraries are needed for programming?
Use the popular Arduino CAN-Bus Shield library by Seeed Studio or the MCP2515 library by coryjfowler, both available on GitHub. They provide simple APIs for sending and receiving CAN messages.
