IMHO you could connect time-sensitive things (like HC-SR04) directly to GPIO-pins, all others things - to expander.jesus_malaga wrote:but I do not want to run out of GPIO pins. Apart of that, the system has some extra hardware
because MCP2515 will produce 5V on his output pins (including those that are connected to PRI)vsboost wrote:"so powering MCP2515 and TJA1050 from 5V will break Pi IOs" why is this so?

Are you out of GPIO pins?skpang wrote:The only thing I'm not sure is the interrupt pin. Both devices is connected to GPIO25 as stated in the overlay. Maybe it need individual pin but it is hard coded at the moment.
