Our THB6064AH driver supports BiPolar motors up to 4 amps/phase at 50 volts... CONTINUOUS!.
New version 1.3 is simpler, less expensive, with top quality for critical parts.
Based on the THB6064AH chip (also known as the Toshiba TB6564AHQ^) which is a design improvement over the TB6560, with better microstepping, lower resonance, and protection for power on sequence (which is a serious problem with the 6560).
NOTE: This is a Kit of parts; you must solder it together. Although easy and well documented, if you haven`t soldered before, please complete our soldering course and the 2 (low cost) projects it suggests before attempting this driver. This kit does not include heatsink, main or logic power supply, motors, or wiring.
SPECIAL PROMOTION (for a limited time): Buy the full parts kit (not for the PCB / chip only options) at the standard price, build it, and then send us your results or post publicly online. We will pay you back $5 for a photo of it up and running. $20 for a video. $10 for a write up including your power supply voltage, motor rating (amps/phase, size, rated torque, etc...) and your review of how it worked (or didn`t) and what you liked (or hated) about the kit. Do all three and the kit is free!
