Supports CAN V2.0B technical specifications, communication speed 1Mb/S 0-8 byte long data field Standard frame, extended frame, and remote frame Module 5V DC power supply, SPI interface protocol control 120ohm terminal resistor. Impedance matching ensures driving capability and prevents signal emission during long-distance data transmission The MCP2515 CAN module is a CAN bus module based on the MCP2515 CAN controller and TJA 1050 CAN transceiver. The modular circuit design is clever and reasonable, the circuit board is exquisite and elegant, and the microcontroller program is simple and easy to understand. The module is powered by a 5V DC power supply and can be easily used on traditional 51 microcontrollers, 51 microcontrollers, ARM and other controllers through the SP protocol. Working current:typical value 5mA, standby current 1uA. (Excluding power indicator lights) Working temperature:Industrial grade -40℃-85℃ Due to different batches, there may be differences in product appearance and printed text, which will not affect use.
