FalCAN Probe is an open-source, STM32-based USB to CAN/RS-485/RS-422 adapter
Most USB-to-bus adapters, including tools like CANTact Pro or MeatPi’s Ollie V1 and V2, typically support either CAN or RS-485/RS-422 as fixed-function serial devices. In contrast, the FalCAN Probe by Anders B. Nielsen is a multi-protocol USB adapter based on the STM32F042 microcontroller. The FalCAN Probe is a compact open-source USB Type-C board that connects a computer to CAN, RS-485, and full-duplex RS-422 networks. Instead of using a fixed USB bridge, it exposes the MCU’s native USB interface along with SWD and GPIOs, and can also be used as a small Arm Cortex-M0 development platform. FalCAN Probe specifications: MCU – STMicro STM32F042C6Tx Arm Cortex-M0 microcontroller @ 48 MHz with 32KB flash, 6KB SRAM Host Interface – USB 2.0 Full Speed via USB Type-C port Interfaces (non-isolated) CAN bus via Texas Instruments SN65HVD230 transceiver; enumerates as a GS_USB CAN device when jumper JP4 is open RS485 and full-duplex RS422 via dual
