Express post delivery (2-5 business days)

The Adafruit RP2040 CAN Bus Feather combines the powerful RP2040 microcontroller with an MCP25625 CAN controller and transceiver, giving you a ready-to-go CAN Bus interface in the compact Feather form factor. No soldering is needed to get started — just connect your CAN Bus lines to the included terminal block and start sending and receiving messages.

CAN Bus is a robust two-wire differential networking standard originally designed for automotive applications but now widely used in robotics, industrial automation, and sensor networks. It offers better range and noise immunity than I2C, with automatic collision detection and retransmission at up to 1 Mbps.

Key Features

  • RP2040 Processor – Dual-core Cortex M0+ at 133 MHz with 264 KB RAM and 8 MB QSPI flash
  • MCP25625 CAN Controller – MCP2515-compatible with built-in transceiver, supporting standard and extended frames at up to 1 Mbps
  • 5 V Charge-Pump – Generates clean 5 V for the CAN transceiver from the 3.3 V Feather power rail
  • 3.5 mm Terminal Block – Solderless connection to CAN High, CAN Low, and ground
  • 120 Ω Termination Resistor – On-board with a cuttable jumper to remove when not at the end of the bus
  • 21 GPIO Pins – Including 4× 12-bit ADC, 2× I2C, 2× SPI, 2× UART, 16× PWM
  • STEMMA QT Connector – Plug-and-play I2C for sensors and peripherals
  • USB Type C – For programming, serial debugging, and power
  • LiPo Battery Support – Built-in 200 mA+ charger with status LED and automatic USB/battery switching
  • NeoPixel + Red LED – RGB NeoPixel for status indication plus pin 13 red LED
