MCP2551 CJMCU-2551 High Speed CAN Controller Bus Interface Modul Arduino

Lieferumfang: 1x MCP2551 Modul ikl Stiftleisten 

This is a fault tolerant high speed CAN device that can be used as a CAN protocol controller and a physical bus interface. The MCP2551 provides differential transceiver capability for the CAN protocol controller, which fully complies with the ISO-11898 standard, including 24V voltage requirements.
Typically, each node on the CAN system must have a device that converts the digital signal generated by the CAN controller into a signal suitable for bus transmission. It also adds a buffer between the CAN controller and the high voltage spikes on the CAN bus, which may be generated by external devices.
Support 1MB / S running speed.
Meet ISO-11898 standard physical layer requirements.
Suitable for 12V and 24V systems. Slope external control to reduce RFI.
Automatically detects a ground fault at the TXD input.
Power-on reset and voltage event undervoltage protection.
No power-up node or undervoltage does not affect the CAN bus.
Low current standby operation.
Up to 112 nodes can be connected.
