This expansion board allows you to expand a Raspberry Pi pico by an RS485 and a CAN interface. In addition, the board can operate it either by means of a standard USB-C connection with 5 V or via a screw terminal that accepts a voltage from 6 to 12 V. The voltage applied to the screw terminal is reduced to 5 V by a voltage converter integrated on the board. https://elecena.pl/product/28015725/joy-it-rb-p-can-485-can-module-for-raspberry-pi-pico 2025-03-12 https://elecena.pl/product/28015725/joy-it-rb-p-can-485-can-module-for-raspberry-pi-pico 2025-09-17
