CAN-BUS, due to its frequent use in industrial applications. CAN-BUS stands out in long-distance transmissions with its moderate communication speed and high security. You can incorporate the preferred CAN-BUS structure, especially in modern machines and complex robot systems, into your circuit using the CAN-BUS Shield. The CAN-BUS Shield utilizes the CAN-BUS transceiver and the SPI-compatible MCP2515 CAN-BUS controller. It can be seamlessly connected to Arduino/Freaduino and Seeeduino boards. With the help of the OBD-II conversion cable and the OBD-II library, you can create an embedded diagnostic device or a data logger. The CAN-BUS Shield also features various communication port supports, analog and digital IOs, and PWM outputs. UART, SPI, and I2C communication ports can be used to communicate with different units. Additionally, the CAN-BUS Shield has 6 analog IO pins, 3.3V and 5V power sources, 6 PWM outputs, and 14 digital IO pins, making it a shield board that enables interaction with different modules. Features: 1 Mb/s V2.0B application 10MHz upward SPI interface Ariduino/Freaduino is fully compatible Standard (11 bits) and extended (29 bits) data and remote frames Industry standard 9-pin Sub-d connector Get two to the main message store function Buffer with DC5-12V operating voltage Size: 78mm x 53.5mm The package includes: 1pc *MCP2515 CAN BUS Shield expansion board Development board CAN communication board Microver is here for your electronic and embedded needs.
