Description
This expansion board allows you to add an RS485 and a CAN interface to a Raspberry Pi Pico.
The board also offers the option of operating it either via a standard USB-C connection with 5 V or via a screw terminal that accepts a voltage of 6 to 12 V. The voltage applied to the screw terminal is reduced to 5 V by a voltage converter integrated on the board.
Features
- Power can be supplied via a USB-C connection with 5 V or via a screw terminal that draws between 6 and 12 V. In the latter case, a built-in voltage converter reduces the voltage to 5 V.
- To increase the versatility and range of functions, the connection pins of the Raspberry Pi Pico have been routed to the outside.
- The expansion board also offers the option of communication via the RS485 and CAN interfaces.
