THB6064AH stepper drive kit pricing 

 

On offer are different kits for each version.

Minimal is the PCB and THB6064AH chip, you will have to source all other components yourself.

Kit with critical components, this includes:
- Low inductance 2Watt SMD current sense resistors.
- Low ESR 470 elco,
- 5K high quality multiturn trimpot for adjusting the motor current.
- LM317T with high voltage input, normal types have a max input of 45VDC for a 5V output, some even lower; this is just not good enough, the back EMF from the motor might kill these and bad things will happen, a 60V input is required.

These parts must be of very good quality for proper operation, resistors wich have some inductance will destabilise the current regulation and cause poor motor smoothness.The elco must have a low esr (equivalent series resistance) as otherwise it will heat up and die prematurely, there are only a few manufacturers wich produce these. The trimpot adjusts the motorcurrent, suppose it's setting fluctuates for whatever reason: it could blow the chip and motor, it will at least cause serious performance problems.
Only buy these yourself if you understand the above component's specs and know what you're doing.

Remainder of the components, these can readily be found but are also the cheapest.
