Project
IC2 is the TMC6300-LA-T motor driver. Its hookup typically involves:
  1. Power Supply & Decoupling:
    • Ensure that its supply pins (for example, the main voltage inputs and VIO/NSTDBY) are connected to the correct power rails.
    • Add decoupling capacitors as specified in the datasheet on each power pin.
  2. Ground Connections:
  3. Control & Interface Signals:
    • Interface its control pins (such as DIAG, 1.8VOUT, U, BRUV, etc.) with your microcontroller (e.g., the ESP1) as needed.
    • Follow the datasheet recommendations for signal levels and required pull-up or pull-down resistors if applicable.
  4. Motor Outputs:
    • If you’re driving a motor, make sure the output pins are routed to your motor circuitry along with any necessary current sensing or protection components.
Could you please clarify which particular aspect of the hookup you need help with? For example:
  • Wiring the power and decoupling network for IC2
  • Interfacing its control pins with the ESP module
  • Routing motor output connections
Let me know and I can provide more specific guidance.

    Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
