Description
Introductions:ST820 is an integrated driver for stepper motors with a built-in converter for easy operation.The product can operate bipolar stepping motors in full, half, 1/4, 1/8, 1/16, 1/32, 1/128 and 1/256 stepping modes.The drive provides a complete range of protection including overcurrent protection, overtemperature protection and short circuit protection.ST820 is a stepper motor driver board that is easy to use on a 3D printer.The drive has fewer external devices and requires no additional components, providing a simpler solution for stepper motor drives.
Supply voltage from 7 V to 45 V.Output current up to 1.5 A rms for each motor phase.Stepper motor driving with a microstepping resolution up to 1/256th of step

Parameter:
1.Motor power supply voltage: 7V---45V2.logic voltage: 3V---5.5V3.the maximum output current: 0A---1.5A4.the largest sub-division: 1/256 subdivision5. drive current: adjustable
Note:
1, the driving ENABLE control signal with 4988, 8729. And the driver signal is the opposite, use the driver to replace the above driver. When, need to modify the firmware ENABLE signal, in the opposite direction. You also need to change the direction.
2. The indoor temperature is relatively high due to the large heat generated during the driving operation. In the case of, please try to choose a lower subdivision or add to the driver. Hot fan prevents excessive temperature from burning the drive.
3. When adjusting the potentiometer setting current, please unplug the motor to avoid burning drive.
4. Do not plug and unplug the motor when it is live, so as not to damage the drive.
5. When installing heat sink, please pay attention to the gap between heat sink and pin pin. Can contact, prevent drive short circuit.
