The TMC2225 module is fully compatible with the DRV8825 and A4988 module pins on the market and can be directly replaced.

product description:
The TMC2225 chip is a stepper motor driver chip that suppresses resonance and is ultra-quiet. It integrates drivers and MOS internally, and its pins are fully compatible with DRV8825; it is extremely cost-effective.
When a common traditional driver chip drives a stepping motor to run, there will be high-pitched noise or motor jitter that is audible to human ears, which seriously affects the experience of the product. Through StealthChop mute technology, TMC2225 can reduce the noise of the stepper motor to less than 10dB when running at low speed, and achieve ultra-quiet performance. It can also use SpreadCycle resonance suppression technology to make the stepper motor run smoothly at high speed without jitter.
