The high-quality MOSFET tube has better heat dissipation effect and ensures stable operation for a long time. Dedicated power chip supports 12V-24V power input, effectively solving the problem of chip heating and insufficient power supply. SPI mode Due to the support of the internal circuit of the motherboard, the SPI mode by TMC2130 or other types no needs , and the settings can be completed by using the jumper . Humanized design Terminals of different colors distinguish the driving direction and reduce the insertion efficiency. Wiring is simple and more stable.
