Boardoza MCP2515 CAN Bus to SPI Breakout Board
Boardoza MCP2515 is a CAN Bus to SPI Converter Module based on the MCP2515 CAN controller and the TJA1050 CAN transceiver. It allows microcontrollers (Arduino, STM32, ESP32, Raspberry Pi, etc.) to communicate over the CAN Bus protocol via a simple SPI interface. The module is widely used in automotive, industrial, and robotics applications. The MCP2515 handles the low-level CAN protocol conversions, while the TJA1050 provides the physical layer interface for differential CAN communication. With MCP2515 module, you can create CAN Bus network with multiple Data sending/receiving nodes without the need of built-in CAN peripherals in microcontrollers.
