The TMC2209 is an ultra-silent motor driver IC for two-phase stepper motors. The driver has a maximum output capacity of 28 V and ± 2 A. It can operate bipolar stepper motors from 1 to 1/256 step modes.
NEMA (National Electrical Manufacturers Association) 34 is a stepper motor with a 3.4×3.4 inch faceplate and 1.8° step angle. Each phase draws 4.0 A, allowing for a holding torque of 42 kg-cm.
The DRV8825 is a Motor Driver with two H-bridge drivers and a microstepping indexer. The driver has a maximum output capacity of 45 V and ± 2.5 A. It can operate bipolar stepper motors in full, 1/2, 1/4, 1/8, 1/16 and 1/32-step modes.
The A4988 is a complete Microstepping Motor Driver with built-in translator for easy operation. The driver has a maximum output capacity of 35 V and ± 2 A. It can operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes.
The XL4015 power module is a DC to DC step-down (BUCK) power module that operates at a switching frequency of 180kHz. In such high frequency, it provides smaller sized filter components compared with low frequency switching regulators.
