2. advantages of the UART 2 modes:
1)The motor current can be arbitrarily set by the firmware;
2)Micro-can be arbitrarily set by the firmware (up to 256 real micro-The real and interpolated micro-can be combined to get the maximum torque;
3)The firmware can dynamically switch the stepper motor between stealthChop2 and spreadCycle mode via the UART;
4)When the motor is not moving, the standby current motor can be dynamically reduced (via the UART)
1.Hardware selection When using the UART operating mode, use a soldering iron carefully to prevent burns and handle after observing, carefully observe whether the module has residual tin slag. It must be cleaned to prevent it.Cause the module to be short-circuited.
2.Pay attention to the line sequence and IO port when wiring. Connecting the wrong line will directly cause the driver to not work.Carefully connected to the above illustration.
3.When plugging the driver into the motherboard, pay attention to see the driving direction, never insert it, and prevent the drive burned.
4.Be sure to do the heat dissipation work (heat sink + cooling fan) before driving to prevent driving.
Note:If you are having trouble using it, or if you need to use the instructions, please contact me after placing your order.
- TMC2208 V2.1 is a newly upgraded driver module. Compared with TMC2208 V2.0, V2.1 puts the chip inside, which is more conducive to heat dissipation.
- TMC2208 single-axis chip stepper motor drive, power supply tube built-in pilot current 1.4A peak current 2A, voltage range of 4.75V-36V, 256 subdivision; With the patented spreadCycle technology of high frequency chopper, dcStep , stall stallGuard2 , sensing technology, CoolStep dynamic current regulation technology, can save 70% energy.
- Flexible microPlyer interpolation unit, the component can provide up to 256 microstep / step resolution, even in the wrist frequency system is limited may still be perfect to achieve sinusoidal control; as stealthChop end music technology is widely used in 3D printing, so that these components are also designed to be compatible with current electronic 3D printer, eliminating the need for expensive redesign. Both components have input pulse / direction, can be completely independent operation. Th
