S109A drive module is based on Toshiba TB67S109 stepper motor driver chip design and production, the use of four thick copper Shen Jin PCB, automatic chip processing. The module uses indexer (DIR / STEP) control interface, can provide up to 4A drive current, can drive 57 stepper motor, and is compatible with Pololu pin definition, can be used directly as a substitute for A4988 module. Main Feature: 1. Use four layers of thick copper immersion gold PCB. 2. Allows full, half, quarter, 1/8, 1/16, 1/32 steps. 3. Maximum input voltage: 50V; maximum output current: 4A (requires good heat dissipation conditions). 4. With a large heat sink, the module can get better cooling effect. 5. High efficiency motor current control (advanced dynamic mixing attenuation ADMD, ADMD technology can more closely track the input current than the traditional mixed attenuation mode, enabling efficient motor control at high speeds). See the TB67S109 chip data sheet for details. 6. On-chip error detection circuit (TSD, ISD, POR) Attention: When using, please be sure to install the heat sink properly and air-cooled, do not run without heat for a long time! 1. The product is sensitive to static electricity. Please handle it carefully when using it. It is best to remove it after use. 2. Please check the installation direction carefully before inserting the module into the motherboard. Improper insertion may damage the motherboard directly. 3. Turn off the power when inserting/removing the module. Do not insert the driver module when the motherboard is powered on. 4. The module will be very hot during work, avoiding touching during work to avoid burns. 5. When installing the heat sink, make sure that the heat sink does not touch the module pins or any other conductive locations.
