The onboard XL2515 CAN controller communicates with the MCU over SPI, while the SIT65HVD230DR transceiver handles the physical differential bus interface, supporting data rates up to 1 Mbps. A selectable 120-ohm terminal resistor simplifies bus termination. The board features the RP2350A's dual-core design with switchable ARM Cortex-M33 and Hazard3 RISC-V processors running at 150MHz, backed by 520KB SRAM and 4MB flash. It exposes 26 multi-function GPIO pins with 2x UART, 2x SPI, 2x I2C, 4 ADC channels, 16 PWM channels, and 12 PIO state machines, all in a Pico-compatible castellated module form factor. Ideal for automotive diagnostics, industrial CAN bus monitoring, vehicle data logging, and custom CAN node development. The CAN interface connects via a screw terminal for reliable wiring in industrial and automotive environments. Programming is supported via MicroPython, Arduino (arduino-pico core), and C/C++ Pico SDK with drag-and-drop UF2 flashing over USB-C. ## Where to Buy - [Waveshare](https://openhardware.directory/r?to=https%3A%2F%2Fwww.waveshare.com%2Frp2350-can.htm&ref=openhardware.directory&product=waveshare-rp2350-can&source=md-export) — 9.99 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.waveshare.com%2Frp2350-can.htm&ref=openhardware.directory&product=waveshare-rp2350-can&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fwww.waveshare.com%2Fwiki%2FRP2350-CAN&ref=openhardware.directory&product=waveshare-rp2350-can&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fdatasheets.raspberrypi.com%2Frp2350%2Frp2350-datasheet.pdf&ref=openhardware.directory&product=waveshare-rp2350-can&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Ffiles.waveshare.com%2Fwiki%2FRP2350-CAN%2FRP2350-CAN-Schematic.pdf&ref=openhardware.directory&product=waveshare-rp2350-can&source=md-export) ## Images ![Waveshare RP2350-CAN](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-rp2350-can/94897a5f220e.jpg) ![Waveshare RP2350-CAN](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-rp2350-can/021ced29723a.jpg) ![Waveshare RP2350-CAN](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-rp2350-can/cd8fec52afd0.jpg) ![Waveshare RP2350-CAN](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-rp2350-can/db59120b7a59.jpg) ![Waveshare RP2350-CAN](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-rp2350-can/51b3ed1e8b04.jpg) --- [View full device page](https://openhardware.directory/devices/waveshare-rp2350-can)
