GPIO Map
Overview
The Waveshare RP2350-CAN is a Pico-compatible development board that combines the Raspberry Pi RP2350A dual-architecture microcontroller with a complete CAN V2.0B bus interface. 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.
