NOT can found, no have, only can use paraller port hat and paraller port breakoutboard, if want rpi use stepper drive direct need voltage level shifter board, 3,3V to 5V 8 pin converter, rpi use 3,3V and convert output can use 5V stuff, etc, stepper motor driver, step and dir pin, and enable pin. and same can bi -directional board use input too 5V sensors,limitSW etc convert to 3,3V and use whit rpi. same output relays etc, cn use gpio pin 3,3V convert to 5V and then use trnsistor who connect to relay on/off relay. gpio not handle lot current about 2mA out and in little more, or burn input/output port. thats why need converter and optocoupler to input current resistor need too, stuff not broken rpi. and shift level converter and resistor output no burn output pin, if have lot money waste buy ower price protoneer rpi cnc shield 100€ horriple price, or cheapen option rpi paraller port hat 35€ and cheap chinese 10€ breakoutboard. i think have possiple use shift level converter to input/output gpio pins and optocoupler cheap in-out system direct to driver and all limit,home,probe,etc inputs, opto input pins and shift level converter output pins, i hope working , i need test if has order all parts, but i not understand what software need do, image were is linuxcnc and how working whit paraller port hat if use, or what need hal file doing or other, programs and code not my job ,not understand anything.
