{"title":"Adafruit CAN Pal - CAN Bus Transciever","handle":"adafruit-can-pal-can-bus-transciever","url":"/products/adafruit-can-pal-can-bus-transciever","description":"The Adafruit CAN Pal is a CAN bus transceiver breakout for microcontrollers that have a native CAN peripheral. It converts 3.3V logic-level CAN TX/RX signals to the differential signalling required for the CAN bus. This is a transceiver only — it does not include a CAN controller, so your microcontroller must have built-in CAN support.\n\nCompatible chips with native CAN peripherals include ESP32, ESP32-S2, and ESP32-S3 (Espressif calls this interface TWAI), SAME51, STM32F405, and Teensy 4. Check your board's documentation to confirm CAN support and that the RX/TX pins are accessible.\n\nKey Features\n\n\nTJA1051/T3 Transceiver – Supports 3.3V–5V logic for use with modern microcontrollers\n\n5V Charge Pump – Generates clean 5V for the transceiver from 3.3V power; no separate 5V supply needed\n\n3.5 mm Terminal Block – Quick access to CAN High, CAN Low, and ground\n\n120 Ohm Termination – 2× 60 ohm resistors in series with onboard switch for easy activation/removal\n\nSimple Wiring – Just connect CAN TX, CAN RX, power, and ground\n\n\n\nNote: This is a transceiver only. Your microcontroller must have a native CAN peripheral (e.g., ESP32 TWAI, SAME51, STM32F405, Teensy 4). Despite sharing the \"RX\" and \"TX\" naming with UART, CAN is a completely different interface.\n\n\nAlso Available\n\n\nAdafruit CAN Bus BFF – CAN controller + transceiver for QT Py / Xiao (SPI interface, no native CAN needed)\n\nAdafruit CAN Bus FeatherWing – CAN controller + transceiver for Feather boards (SPI interface, no native CAN needed)\n\n\nIdeal For\n\nESP32-based CAN bus projects using TWAI\nRobotics and sensor networks\nAutomotive and industrial CAN interfacing\nProjects using microcontrollers with native CAN peripherals\n\n\nPackage Contents\n\n1× Adafruit CAN Pal transceiver (assembled)\n1× 3.5 mm terminal block\n1× Header strip\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1674,"title":"Default Title","sku":"AF-5708","price":8.25,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
