Notes / Hints
- The TMC22xx and TMC516x drivers have an improved stealthChop mode (stealthChop2), which works better on higher accelerations.
- The resistance of the TMC22xx output drivers (RDSon) are a bit lower compared to the TMC21xx, which gives a lower power dissipation.
- The TMC2209 drivers with UART interface have a few more features, which can be used for motor current setting via software or sensorless homing when the driver is connected via UART to the mainboard.
- The TMC2130 and TMC516x drivers with SPI interface have a few more features, which can be used for motor current setting via software or sensorless homing when the driver is connected via SPI to the mainboard.
- If the power up/down sequences for SilentStepSticks with variable logic voltage (3-5V) can not be ensured, then we strongly recommend the SilentStepStick Protector.
