MCP2515 CAN Bus Module with TJA1050 Transceiver – SPI Interface for Arduino, ESP32, Industrial & Automotive (OBD2) Applications.

✨ Key Features & Benefits

Industrial-Grade Reliability & Wide Temperature Range: Operates from -40°C to +85°C, suitable for harsh industrial and automotive environments.

High-Speed CAN 2.0B Support: Communication speeds up to 1 Mbps for real-time data acquisition and automotive diagnostics.

Simple SPI Interface: Easy connection to Arduino, ESP32, Raspberry Pi, and other MCUs via standard SPI.

Onboard 120Ω Termination Resistor: Enabled via jumper to ensure stable long-distance communication and noise immunity.

Ultra-Low Power Consumption: ~5mA operating current, 1μA in standby, ideal for power-sensitive designs.

📦 Product Description
Bridge your microcontroller projects to the professional world of CAN Bus. The MCP2515 module handles the complex protocol, allowing you to focus on reading and sending data. Whether for vehicle OBD-II diagnostics, industrial equipment networking, robotics, or marine/agricultural communications, it's the core component for reliable multi-node communication.

⚠️ Important Notes (Proactively Prevent Negative Reviews)

【Interface & Logic Levels】 Uses 5V Logic! This module operates at 5V, and its SPI logic levels are 5V. When connecting to a 3.3V host (e.g., ESP32, Raspberry Pi), you MUST use a logic level converter to avoid damaging the 3.3V device!

【Termination Resistor】 Enable Based on Network Topology: The 120Ω termination resistor should be enabled only on the two end nodes of a CAN bus. If your module is in the middle, leave the jumper off.

【Wiring】 Use Twisted Pair for CANH/CANL: To reduce interference, connect the CAN bus using a twisted pair for CANH and CANL, with the shield grounded.

【Power】 Provide a Stable 5V Supply. Power supply noise can affect communication stability.
