Main components
1README
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 Shield pcb PCB?
It measures 165.3 × 115.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shield pcb use?
76 parts, built around the RJ45. 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 Shield pcb KiCad files?
From the sami-klibi/PCBs repository on GitHub, at the commit this page was made from: the board is Servo POE/board 1/shield pcb.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 Shield pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask sami-klibi before reusing the design.
