JP660 (Customer) asked a question.
Can a P1AM controller be connected to a stepper driver through the GPIO module?
I am attempting to create a syringe pump but using standard caulking tubes. I would like to use a stepper motor connected to a precision ball screw linear actuator to precisely move the plunger rod a specific distance. I have been able to move the plunger rod with an Arduino MEGA2560 R3 board, but on the GPIO module there is not a 5V power output. which I used for the trigger button. Can the 3.3 V VCC of the GPIO module be used instead?
Thanks
I have used logic level converters for things like this. Pretty cheap.
Amazon and others have items like 4-Channel Optocoupler Photoelectric Isolator Module Level Voltage Converter. NOYITO.
Many optoisolator-based modules and SSRs accept the P1AM's 3.3V 7mA but most have a very low current output. I have some success with the DONGKER module, available through Amazon, which allows me to pulse all of my motor drives except for the one requiring 10mA inputs. Does anyone know of such a module that can output 10mA (guaranteed current transfer ratio of 150%)? It can be a module or a chipset, sinking or sourcing, 24V (preferred), 12V or 5V, and capable of 4000Hz.
