Adafruit CAN Pal - CAN Bus Transceiver - TJA1051T/3

The Adafruit CAN Pal Transceiver is a handy solution for connecting boards with native CAN peripheral support to the CAN bus network. It takes 3V logic level signals from microcontrollers and converts them into CAN logic levels with the required differential signaling for communication. It's important to note that not all chips come with a CAN peripheral, so ensure your board supports CAN, such as the ESP32/ESP32-S2/ESP32-S3, SAME51, STM32F405, or Teensy 4.

Key Features:

• CAN Bus Compatibility: Supports the CAN Bus, a small-scale networking standard that is widely used in cars, buses, robotics, and sensor networks. It’s excellent for applications requiring long-distance communication in noisy environments.
• Differential Signaling: The transceiver converts logic levels to CAN's differential signaling, providing stable communication even in challenging environments.
• Message Handling: CAN messages are transmitted at 1 Mbps rate, with nodes synchronizing to the bus frequency. Nodes can easily be added to the network and will automatically handle message collisions and retransmit if needed.

Added Extras:

• Wide Voltage Range: The TJA1051/T3 transceiver can communicate with logic levels from 3.3V to 5V, making it compatible with modern microcontrollers.
• 5V Charge-Pump: The integrated 5V charge-pump voltage generator allows the transceiver to work seamlessly even when running on 3.3V logic, eliminating the need for a separate 5V power source.
• Termination Resistor: The board includes two 60-ohm termination resistors in series, which you can easily enable or disable with an onboard switch.
• Terminal Block: A pre-soldered 3.5mm terminal block provides quick access to the High and Low data lines and ground for easy wiring.

Each order includes a fully assembled transceiver with a pre-soldered terminal block and header. You'll need to solder the header to use the breakout with your breadboard or project, but it’s a simple and quick task.

Whether you’re setting up a robotics project, sensor network, or automotive application, the Adafruit CAN Pal Transceiver makes it easier than ever to integrate CAN communication with modern microcontrollers!
