1. The working voltage is DC 10V-35V. It is recommended to use a switching power supply DC24V for power supply.
2. Using 6N137 high-speed optical coupling to ensure high speed without losing step.
3. Using Toshiba TB6560AHQ chip, there are built-in low-voltage shutdown, overheating shutdown and overcurrent protection circuits to ensure performance.
4. The rated output (max) is: +/-3A, with a vertex value of 3.5A.
5. It is suitable for two-phase/four-phase/four-wire/six-wire stepping motor with 42,57 stepping within 3A, but not suitable for stepping motor with more than 3A.
6. Automatic half-flow function.
7. Subdivision: Full step, half step, 1/8 step, 1/16 step, maximum 16 subdivision.
8. Dimensions: Width 50 x length 75 x height 35 (MM)
9. Weight: 83G
10. This module does not have any protection circuit, so you must be very careful when using it, otherwise the chip is easy to burn out.
