Schematic Description

The schematic details the TMC2210 stepper motor driver IC (IC201) and its associated components. It outlines connections for power (VM, GND, VCC_IO, VDD1V8), motor phases (OUT1A, OUT2A, OUT1B, OUT2B), control signals (STEP, DIR, DRV_ENn, INDEX, ERROR), and configuration pins (CFG0-CFG7). Decoupling and filtering are provided by capacitors (C201-C208). Resistors (R201, R202) are used for IREF setting and other functions, with the potentiometer (EVMSR) connected to IREF.
