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.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCAN Controller\u003c\/td\u003e\n\u003ctd\u003eMCP2515 (SPI interface)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCAN Transceiver\u003c\/td\u003e\n\u003ctd\u003eMCP2551\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProtocol Support\u003c\/td\u003e\n\u003ctd\u003eCAN V2.0B, 1 Mb\/s max\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicroSD Slot\u003c\/td\u003e\n\u003ctd\u003eYes (SPI shared with CAN)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eConnector\u003c\/td\u003e\n\u003ctd\u003e2-pin screw terminal\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Arduino shield size (68.6 x 53.4 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eOBD-II automotive diagnostic tool to read ECU data\u003c\/li\u003e\n  \u003cli\u003eIndustrial sensor network over CAN bus\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-can-bus-vehicle-data-logger\"\u003eVehicle data logger with timestamps on microSD\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eSmart home CAN node for lighting or HVAC control\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eDesigned 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.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eSimply 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery 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.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Mega?\u003c\/summary\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes it include a microSD card?\u003c\/summary\u003e\u003cp\u003eNo, the microSD card is not included. You'll need to supply your own FAT16\/FAT32 formatted card, up to 32 GB in capacity.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat libraries are needed for programming?\u003c\/summary\u003e\u003cp\u003eUse the popular Arduino CAN-Bus Shield library by Seeed Studio or the MCP2515 library by coryjfowler, both available on GitHub.
