STM32 USB CAN Analyzer Flexible

Housing material: Black plastic. Electrical protection: Integrated TVS diode for suppression of surge and transient spike voltages. Core controller: Industrial-grade STM32 microcontroller ensuring deterministic timing and error-free frame handling under sustained bus load. Protocol support: CAN 2.0A (11-bit identifier) and CAN 2.0B (29-bit identifier). Adjustable CAN bit rate: 5 kbps – 1 Mbps in fine-grained steps — covering legacy truck ECUs (e.g., 250 kbps), modern EV battery BMS (500 kbps), and fast diagnostic channels (1 Mbps). Operational modes: normal (transmit/receive), loopback (internal TX→RX verification), silent (monitor-only, zero bus loading), silent loopback (fully isolated self-check). Transmission flexibility: supports one-off messages, multi-packet sequences, user-triggered sends, scheduled intervals, and continuous cyclic transmission at defined intervals. Reception can be narrowed to specific CAN IDs or set to automatically reply with pre-defined payloads — useful for simulating sensors or gateways. Time-stamped message display enables chronological reconstruction of bus activity. USB CDC ACM interface offers configurable baud rates from 9600 to 2,000,000 bps (factory default 2 Mbps), ensuring compatibility with legacy and modern host systems. Configuration is persistent across power cycles via built-in flash memory. Comes with Windows desktop software for visual setup and live monitoring; also supports headless operation via serial AT commands.
