CAN Isolator Click

CAN Isolator click provides isolated CAN communication. It carries the ADM3053 signal and power isolated CAN transceiver with an integrated isolated DC-to-DC converter, from Analog Devices. The click is designed to run on either 3.3V or 5V power supply. CAN Isolator click communicates with the target microcontroller over UART interface.

The click carries a DB 9-pin male connector.

ADM3053 features

The ADM3053 is an isolated controller area network (CAN) physical layer transceiver with an integrated isolated DC-to-DC converter.

The ADM3053 creates a fully isolated interface between the CAN protocol controller and the physical layer bus. It is capable of running at data rates of up to 1 Mbps.

Connector features

This is a standard DB 9-pin male connector.
