Key Features:

• MCP2515 CAN controller + TJA1050 CAN transceiver

• Communicates via SPI protocol

• Fully compatible with Arduino, STM32, AVR, and 8051 microcontrollers

• Supports 11-bit and 29-bit identifier CAN frames

• Up to 1Mb/s CAN communication speed

• Used in automotive diagnostics, industrial CAN networks, and IoT systems

Product Description (Detailed):

The MCP2515 CAN Bus Module with TJA1050 Transceiver enables controller area network (CAN) communication between microcontrollers and CAN-enabled devices. It uses MCP2515, a stand-alone CAN controller, and TJA1050, a high-speed CAN transceiver, for reliable communication over long distances.

This module connects to your Arduino, STM32, or ATmega microcontroller via SPI interface and allows you to send and receive CAN frames with precise timing, making it ideal for automotive ECUs, CAN-based sensors, motor controllers, and industrial automation systems.

How to Use:

1. Connect module to Arduino (or MCU) via SPI:

   • VCC → 5V, GND → GND, CS → D10, SO → D12, SI → D11, SCK → D13

2. Connect CAN_H and CAN_L to another CAN device or module.

3. Use "MCP_CAN_lib" or "Seeed Studio CAN library" for Arduino.

4. Initialize CAN communication in your Arduino code:

    
   #include <mcp_can.h>
   #include <SPI.h>
   MCP_CAN CAN0(10); // CS pin
   void setup() {
     Serial.begin(115200);
     while (CAN_OK != CAN0.begin(CAN_500KBPS)) {
       Serial.println("CAN BUS Init Failed");
       delay(100);
     }
     Serial.println("CAN BUS Shield Init OK!");
   }

5. Send/receive CAN messages as needed.

Note: Always use proper termination on both ends of the CAN bus (120Ω).

Applications:

• Automotive ECU communication & diagnostics (OBD-II)

• Industrial CAN networks

• Electric vehicles and battery management systems (BMS)

• CAN-based motor control

• Distributed sensor and actuator systems

• Robotics and automation with real-time communication
