CAN Isolator click

MIKROE-2627

33 g

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.

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 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.
