It is simple to use and operate using an indexer (DIR\/STEP) interface to move the stepper motors. The SD6128 is a drop-in replacement for Pololu style footprint drivers including the SD8825, A4988, A4983 and Stepsticks. One distinct feature of the SD6128 is that heat pad is located at the top of the chip. This makes heat sinking a lot easier and does not rely on the already small PCB area for heat dissipation.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e- Made with 4 Layer RoHS PCB\u003cbr\u003e- 1, ½ , ¼, ?? 1\/16, 1\/32, 1\/64 and 1\/128 Microstepping\u003cbr\u003e- Up to 2.2A peak drive current\u003cbr\u003e- Top mounted heat pad\u003cbr\u003e- Larger heat sink mounting area\u003cbr\u003e- Easy to use DIR\/Step interface\u003cbr\u003e- Output pins for Decay and external Vref\u003cbr\u003e- Driver Chip:THB6128 with over current and over temp protection\u003cbr\u003e- Current Motor Supply : 2.2A max\u003cbr\u003e- Motor Voltage: 35V max\u003c\/span\u003e\u003cp hiragino=\"\" sans=\"\" style=\"margin: 0px; padding: 0px; line-height: 1.5; clear: both; color: rgb(51, 51, 51); font-family: \"\u003e \u003c\/p\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003ePin function:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"\" src=\"https:\/\/img.staticbg.com\/images\/oaupload\/banggood\/images\/FA\/85\/cd8ad953-9184-4854-a8a6-2e502b57eb4c.jpg\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eInterface Resource:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"\" src=\"https:\/\/img.staticbg.com\/images\/oaupload\/banggood\/images\/F5\/A4\/8e33326e-8672-4c9d-b684-e13427b09a8c.jpg\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cdiv\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eMotor Current Setting\u003c\/strong\u003e\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eThe current limit can be adjusted by measuring VREF and turning the trimmer (see FIG.1).
