ATOM CAN

SKU:K057

Description

ATOM CAN is a CAN bus communication unit that uses the CA-IS3050G transceiver solution (the built-in DC-DC isolation power chip can effectively isolate interference and prevent damage to sensitive circuits). The communication bus can support up to 110 nodes, the signal transmission rate can reach 1Mbps, and it has a variety of electrical line protection functions. It is very suitable for application scenarios such as in-vehicle transportation and security systems.
