No soldering is needed to get started — just connect your CAN Bus lines to the included terminal block and start sending and receiving messages.\n\nCAN 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.\n\nKey Features\n\n\nRP2040 Processor – Dual-core Cortex M0+ at 133 MHz with 264 KB RAM and 8 MB QSPI flash\n\nMCP25625 CAN Controller – MCP2515-compatible with built-in transceiver, supporting standard and extended frames at up to 1 Mbps\n\n5 V Charge-Pump – Generates clean 5 V for the CAN transceiver from the 3.3 V Feather power rail\n\n3.5 mm Terminal Block – Solderless connection to CAN High, CAN Low, and ground\n\n120 Ω Termination Resistor – On-board with a cuttable jumper to remove when not at the end of the bus\n\n21 GPIO Pins – Including 4× 12-bit ADC, 2× I2C, 2× SPI, 2× UART, 16× PWM\n\nSTEMMA QT Connector – Plug-and-play I2C for sensors and peripherals\n\nUSB Type C – For programming, serial debugging, and power\n\nLiPo Battery Support – Built-in 200 mA+ charger with status LED and automatic USB/battery switching\n\nNeoPixel + Red LED – RGB NeoPixel for status indication plus pin 13 red LED\n\n\nAlso Consider\n\n\nFeather RP2040 – Standard RP2040 Feather without CAN Bus\n\n\nIdeal For\n\nAutomotive diagnostics and OBD-II projects\nRobotics and motor controller networks\nIndustrial sensor networks and automation\nMulti-node embedded communication systems\n\n\nPackage Contents\n\n1× Adafruit RP2040 CAN Bus Feather (assembled and tested)\n1× Header strip (soldering required for FeatherWing stacking)\n\n\nResources\n\nCircuitPython MCP2515 Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1620,"title":"Default Title","sku":"AF-5724","price":40.41,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
