Description M5Stack Atomic CAN Base is an ATOM CAN Bus base for adding isolated CAN communication to ATOM series controllers. Built around the CA-IS3050G CAN transceiver, this isolated CAN communication module includes an isolated DC-DC power design to reduce interference and protect sensitive circuits in vehicle equipment control, industrial field control, and CAN bus communication systems. The M5Stack Atomic CAN Base supports CAN bus multi-point communication with up to 110 nodes, a signal rate up to 1Mbps, low loop delay, and common-mode voltage from -12V to 12V. For ATOM Matrix, ATOM Lite, ATOMS3, and ATOMS3 Lite projects, this ATOM CAN Bus base is a compact way to build a CAN bus communication interface without designing a separate transceiver board. Features CAN bus multi-point communication: supports up to 110 nodes for scalable CAN bus communication networks. CA-IS3050G CAN transceiver: designed for isolated, reliable differential communication. Built-in isolated DC-DC: the isolated CAN communication module helps reduce interference and protect circuits. Up to 1Mbps signal rate: suitable for fast industrial control and vehicle equipment control data exchange. Protection functions: common-mode voltage range of -12V to 12V with signal protection for harsh electrical environments. ATOM ecosystem fit: the ATOM CAN Bus base works with ATOM Matrix, ATOM Lite, ATOMS3, and ATOMS3 Lite.

Vehicle equipment control prototypes that need a compact CAN interface. Industrial field control networks with isolated communication requirements. Security system controllers and distributed device monitoring nodes using an ATOM CAN Bus base. ATOM-based test tools using an isolated CAN communication module and CA-IS3050G CAN transceiver for robust wiring. Choose this board when a compact ATOM project needs CAN bus communication, vehicle equipment control, or industrial field control without building a CAN transceiver circuit from scratch. The ATOM CAN Bus base is also useful when an isolated CAN communication module must stay small and easy to mount. Product List 1 Atomic CAN Base 1 HT3.96-4P Terminal Other Content The schematic and model size references are useful when mounting the M5Stack Atomic CAN Base in an enclosure or verifying the HT3.96-4P terminal wiring for CANH, CANL, power, and ground. For ATOM-based CAN bus communication, the base form factor keeps wiring short and installation clean. The CA-IS3050G CAN transceiver is the key hardware part for the isolated CAN link. The CA-IS3050G CAN transceiver and isolated DC-DC design make the board more suitable for noisy control wiring than a simple non-isolated CAN adapter.
