What is it?

CAN-BUS is a common industrial communication bus because of its long travel distance, medium communication speed, and high reliability, it is the backbone of many protocols with applications in automation, industrial systems, building management.

This Maduino Zero CAN-BUS based on SAMD21G18A, with the CAN controller MCP2515 and CAN transceiver MAX3051, to create a ready-to-use CAN-bus port. With this board, you can easily get/send your local data remotely with a standard CAN Bus. For example, you can collect local sensor data, using the Maduino zero ports, and send all the data to remote servers, to create remote-monitor with reliable CAN-Bus communication. To ensure this board easy to use in application, for the CAN-BUS, there are both the common 2.54mm connector and standard DB-9 connector. You can easily use the standard DB-9 cable, or normal jumper wires, to connect this board to your local CAN-BUS, and even more, you can connect this board to OBDII devices such as vehicles, with the DB9 to OBDII cable.

Besides, there also the common RS-485 ports that you can use this board to create local RS485 communication.

Note: This is a soldered board as my photos show, but the pins are not soldered.
