This expansion board allows you to add an RS485 and a CAN interface to a Raspberry Pi Pico. The board can be operated either via a standard USB-C connection with 5 V or via a screw terminal that accepts an input voltage of 6 to 12 V. The voltage applied to the screw terminal is reduced to 5 V by an integrated voltage converter. Specifications - Interface CAN: SPI, CAN - Interface RS485: Serial RS485 - Supply voltage: USB-C 5 V DC / screw terminal 6-12 V DC - Logic level 3.3 V - Terminating resistor CAN: 120 Ohm (can be deactivated if required) - Terminating resistor RS485: 120 Ohm (can be deactivated if required) Note:The USB-C connection does not transmit any data to the Raspberry Pi Pico
