Stepper driver with remote?

[jaru-eri]

I see a lot of these on ebay, but does anybody her know how much force they can give to 12-14v motors?

what do you want to use the stepper remote control for ???

the torque from any motor connected to the board will be very low
as the motor supply voltage is the same 5V that also powers the ATMEL AT89V2051



the part number of the stepper driver on the under side of the board is unreadable



from the advert
"Input Voltage: DC4 ~ 6V / 300 ~ 500mA (so we can input by any battery (not Included), or usb power supply"


if you ignore the current taken by the ATMEL controle IC
the maximum current available for the motor is 500mA (0.5A)
OK for the small stepper motors in DVD , Floppy drives etc

check the resistance of the coils in the 12V stepper motor you want to use

you may find the resistance is high enough to limit the motor current instead of the stepper driver IC

the low voltage (5V) will also limit the maximum speed you can step the motor

Are there stronger remote controlled drivers for sale on the web which may be better?

Connect the one you linked to a driver and the driver to a power supply. That way you can use more powerful motors, but it is going to need mains supply due to the voltage and current needs. There is no way you can drive powerful motors without a very large battery or a real power supply.

The microcontroller is probably not outputting step/direction but instead driving the dual h switch on the bottom side directly. I’m assuming the 10 pin chip is some kind of basic driver due to its low output power. I don’t know of any 10 pin stepper driver chip that has step direction inputs.

You can replace that bottom driver with one that has more output current capability I suppose, If that is what you mean. Hopefully OP has some basic electronic skills to do that.

this could be a solution if you substitute the TB6560 stepper driver with something like a TB6564AHQ driver :-

Its not obvious from the advert how the control boards is switched between driving a motor and outputting step & direction signals
