M5Stack Atomic CAN Base – Isolated CAN Bus Module, 1 Mbps
Product Overview
The M5Stack Atomic CAN Base is a compact CAN bus communication expansion base designed for M5Stack ATOM-series controllers. It uses the CA-IS3050G CAN transceiver and integrates an isolated DC-DC power supply to help reduce electrical interference and protect sensitive circuits.
The module supports a maximum data rate of 1 Mbps and up to 110 nodes on a single CAN bus. Its low loop delay of 150 ns, −12 V to +12 V common-mode voltage range, and CAN signal-line protection make it suitable for vehicle equipment control, industrial field systems, and distributed CAN communication networks.
