CAN module TJA1050 / MCP2515 (SPI CAN)

Buy a TJA1050 / MCP2515 CAN module for reliable device communication

The module is built on Microchip (MCP2515) and NXP (TJA1050) chips. These manufacturers produce a wide range of CAN controllers and drivers. The range includes analogues for different voltages and speeds. This module is popular in DIY projects.

• Supports CAN V2.0B with data up to 1 Mbit/s.
• SPI interface with frequency up to 10 MHz.
• Built-in 120 Ohm termination resistor.
• Wide supply voltage 2.7–5.5 V.
• Operating temperature from -40 to +85°C.

How the CAN module works

The MCP2515 chip converts SPI signals into CAN messages. The TJA1050 driver amplifies the signal for transmission over the bus. A built-in 120 ohm resistor terminates the line. You connect the module to Arduino or STM32. Your device communicates with other CAN nodes.

Technical characteristics and functionality

The module complies with the CAN V2.0B standard. The maximum transfer speed is 1 megabit per second. The supply voltage is in the range of 2.7–5.5 V. The SPI control interface operates up to 10 MHz. The current consumption is 5 milliamps. Operating temperature from -40 to +85°C. There is a 120 Ohm termination resistor. Board dimensions 40x28x12 mm.

The module allows you to connect microcontrollers to the CAN bus. It is widely used in automotive electronics. Used in control systems for drones and robots. Suitable for industrial automation and smart home. You can use a jumper to disable the built-in resistor if necessary.
