It is built around the TMC2209SILENTSTEPSTICK and LM2596S-ADJ. Its parts include 5 resistors, 4 capacitors, 4 diodes, 4 connectors and 3 ICs. It belongs with the ESP32 boards of this library.
Main components
2README
ESP32_Shield/README.mda custom shield designed for the ESP32, aimed at centralizing and simplifying the control of various system components. This board integrates several essential elements:
🧠 A dedicated slot for the ESP32, ensuring a clean and stable integration of the microcontroller.
🔄 A TMC2209 stepper motor driver, used for quiet and precise motor control.
🔋 An LM2596 voltage regulator, selected with the help of the datasheet [5], to provide a stable power supply to the system.
🔔 An integrated buzzer for simple audible alerts.
💡 Status indicator LEDs, to visually monitor the state and operation of the system.The shield also includes several connection ports:
⛓️ A port for a limit switch used for homing and position detection.
🔗 An I2C communication port for connecting servo motor driver boards (e.g., PCA9685).
🔌 A port for the stepper motor connection.
🌬️ A port for a cooling fan, ensuring efficient thermal management.This shield provides a centralized, compact, and efficient management solution for the system’s hardware, reducing wiring complexity and improving physical integration within the enclosure.

Questions
How big is the Esp32 driver PCB?
It measures 73.5 × 71.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32 driver use?
23 parts, built around the TMC2209SILENTSTEPSTICK and LM2596S-ADJ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Esp32 driver KiCad files?
From the sami-klibi/PCBs repository on GitHub, at the commit this page was made from: the board is ESP32_Shield/esp32_driver.kicad_pcb and its schematic ESP32_Shield/esp32_driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask sami-klibi before reusing the design.
