SN65HVD230 CAN Transceiver Module

The SN65HVD230 CAN Transceiver Module is a compact 3.3V interface board built around Texas Instruments’ widely trusted SN65HVD230 IC, designed to bridge microcontrollers with a CAN (Controller Area Network) bus. It’s an essential building block for anyone working on automotive diagnostics, industrial automation, robotics, or multi-node sensor networks where reliable, noise-resistant communication over long distances is required. This CAN bus module, sometimes referred to as a CAN interface board, converts the single-ended CAN protocol signals from your microcontroller’s CAN controller into the differential signaling used on the physical CAN bus, and vice versa.

Compliant with the ISO 11898-2 high-speed CAN physical layer standard, the module supports data rates up to 1 Mbps, making it suitable for real-time applications like engine control units, industrial PLCs, and distributed sensor arrays. It features robust protection circuitry including high ESD immunity, bus fault protection, and thermal shutdown, ensuring reliable operation even in electrically noisy environments. A low-power standby mode is also supported, allowing efficient power management in battery-operated or always-on systems. Pairing easily with Arduino, ESP32, STM32, and other 3.3V logic microcontrollers running a CAN controller, this module is ideal for hobbyists and engineers building CAN-based networks or prototyping vehicle communication systems.
