Adafruit RP2040 CAN Bus Feather with MCP2515 CAN Controller

If you'd like to quickly get started with CAN bus interfacing, our Adafruit RP2040 CAN Bus Feather is ready for immediate use with no soldering required. It features a microcontroller, CAN chipset, and terminal blocks.

The MCP25625 controller, similar to an MCP2515 with a built-in transceiver, offers support in Arduino and CircuitPython. It connects using an SPI port and requires only two pins for chip-select and IRQ, effectively sending and receiving messages in both standard and extended formats at up to 1 Mbps.

Feather boards, known for their light and portable design, are equipped with an RP2040 chip clocked at 133 MHz. The chip includes 8 MB of QSPI FLASH and 264K of RAM.

This compact board (2.0" x 0.9" x 0.28") weighs just 6.3 grams, and offers 21 GPIO pins, multiple I2C, SPI, and UART peripherals, and built-in PWM outputs. Additional features include a 200mA+ Li-poly charger, RGB NeoPixel, and a STEMMA QT connector.

Specifications highlight easy connections and reliable performance: 5V charge-pump generator for the transceiver, soldered terminal block, 120-ohm termination resistor (removable), and LED indicators for status updates.

The USB Type C connector ensures seamless power and data transfer. Enjoy peace of mind with around-the-clock integrated battery charging, making it perfect for portable projects that automatically switch to USB power when available.
