Description

The KAmod CAN TJA1051 CAN transceiver module enables communication between a CAN controller and the physical CAN bus using the NXP TJA1051T/3 chip. The transceiver converts the controller's digital TX and RX signals into differential CAN-H and CAN-L signals and performs conversion in the opposite direction. It supports data transmission at speeds up to 1 Mbps and works with microcontrollers equipped with a hardware CAN controller or external CAN controllers providing the appropriate signal lines. The module is suitable for automation systems, robotics, control devices, and projects requiring data exchange over a CAN bus.

The built-in step-up converter allows the module to operate with a supply voltage of 3 V to 5 V, ensuring proper transceiver operation even in systems powered by 3 V. The logic levels of the RX and TX signals correspond to the voltage supplied to the VCC input. The module provides an SLNT input for activating Silent mode, in which the bus transmitter is disabled while data reception remains active. This function allows CAN communication to be monitored without transmitting data onto the bus.

The board features a switchable 120 Ω termination resistor that can be connected between the CAN-H and CAN-L lines. The resistor should be enabled when the module is located at one of the bus ends requiring termination. A 7-pin connector with a 2.54 mm pitch is provided for connecting the CAN controller, while the CAN bus can be connected through a 3-pin Phoenix MC connector with a 3.81 mm pitch. The board measures 32 x 19 mm and has two mounting holes with a diameter of 3.2 mm. Detailed information about the pinout, power supply, and connection method is available in the KAmod CAN TJA1051 documentation.
