Wiring Guide
1. VCC : Connect 12-30V power supply ( Refer to the working voltage of the motor, general 24V )
2. GND: Ground wire
3. CLK : Control signal (Connected to pulse input )
4. DIR: Direction control signal ( Floating forward, ground reverse )
5. ENA: Connect to enable signal ( Default enable, grounding stops working )
6. P2: Connect one phase to the motor on each side ( Refer to the motor parameter description, the motor is divided into two phases AB, pins 1 and 2 are connected to one phase, and pins 3 and 4 are connected to the other phase. )
DIP Switch Operation
DIP switch {ON (1) / OFF (0)}:
- Div1, Div2 control pulse frequency division
(1) 00: 4 subdivision
(2) 10: 8 subdivision
(3) 01:16 subdivision
(4) 11:32 subdivision
- Ctl setting control mode, open-loop / closed-loop
(1) 0 : Open-loop mode
(2) 1 : Closed-loop mode
- AC setting calibration
Turn the AC to position 1, and turn on the power. The LED blinks 3 times to start automatic calibration. The motor shaft rotates counterclockwise for one cycle and then clockwise for one cycle. The system automatic calibration complete and the LED continues to flash. The AC dial returns to position 0, and then restart power.

Bed Sheets
Color: Bright White Striped, Size: Queen
I’m really happy with these bed sheets. They feel soft and comfortable against the skin, and the crisp white color gives the bed a clean, fresh look. The fabric is lightweight but still feels durable and well made. They fit the mattress nicely and stay in place throughout the night. After washing, they came out looking great with no noticeable shrinking or loss of softness.

Great sheet set
Color: Blush Pink, Size: Full
Super soft right out of the package. Thin material but should be perfect for cool nights. Blush pink is the perfect shade of pink. Love this set. Highly recommended especially at this price point.

Perfect Lightweight Sheets for Sensitive Hot sleepers
Color: Cream, Size: Queen
These sheets are soft, thin, and absolutely perfect for me. I have advanced CRPS and erythromelalgia, so I deal with severe nerve burning and heat sensitivity and cannot tolerate being overheated at all. I keep our AC between 56–64 degrees constantly, and since our studio is small, it usually stays around 61–63.
These sheets have been a lifesaver for sleep. They are lightweight, breathable, and don’t trap heat, which helps me avoid extreme flare-ups and the intense burning pain I deal with. I'm bedridden so I need to be comfortable. They feel comfortable against my skin and don’t worsen my symptoms when I’m already in a lot of pain and look nice, wash nicely.
For the price, they are also a great value. I’m genuinely grateful to have found something that helps me rest more comfortably. Will be buying more for us and gifts.

Solid edger for the price!
Easy to assemble and works well for my needs edging the driveway and sidewalk! Reasonable price and seems fairly well made so far! I’ve only used it a couple of times but does the job well!
