I am looking for a USB (com interface) that will allow me to control at least 3 relays, 1 input, and 4 outputs. Any suggestions and thanks?
Edit: forgot 3 analog inputs preferably 12 bits
Edit 2: Well since I haven’t used they maybe I better be clearer. I need three PID controllers. So 3 of the output need to be PWN. Maybe I read wrong, but I thought PWM was a standard option.
