MCP2515

The MCP2515 CAN Bus Module uses the MCP2515 CAN controller and TJA1050 transceiver to add CAN V2.0B communication to any SPI-capable microcontroller (Arduino, STM32, etc.). Supports standard, extended, and remote frames. Up to 1Mbps. Selectable 120Ω termination resistor (J1 jumper). Dual CAN output: KF301 screw terminal (J2) and pin header (J3). 8MHz crystal oscillator.

Pin Configuration (SPI side):

• VCC — 5V
• GND — Ground
• CS — SPI chip select (active low)
• SO (MISO) — SPI data out
• SI (MOSI) — SPI data in
• SCLK — SPI clock
• INT — Interrupt output
