The module bridges low-voltage microcontroller logic lines with differential high-voltage automotive networks using an intuitive dual-row or linear pin mapping layout: Primary Function / Connection Connects to a standard 5V regulated power supply. GND Common reference ground for the system circuit. TXD / TX

For a CAN bus network to operate without signal reflections, the physical ends of the bus must be terminated. The WCMCU1051 module typically comes pre-assembled with a onboard connected across the CAN_H and CAN_L traces. Wiring to a Microcontroller (e.g., ESP32 or STM32) Note: For proper bus function across long distances

3.0V - 5.5V (Compatible with both 3.3V and 5V microcontrollers like Arduino and ESP32) Data Rate: Up to
