🔹 Pin Configuration & Wiring
⚠️ Direct MCU GPIO Connection Hazard
Desoldering Pump – Solder Sucker is an inductive electro-mechanical load drawing up to 200mA – 1A+ surge current. An ESP32 GPIO pin is rated for only 12mA (Arduino Uno is rated for 20mA).
Never wire this motor directly to ESP32 / Arduino pins. Doing so will immediately destroy the microcontroller's output transistors due to inrush current and reverse back-EMF inductive voltage spikes. Always use an intermediate motor driver or transistor switch with a common ground.

Power Architecture Guidelines:
• Nominal Voltage: 3.7V - 6V DC
• Common Ground (GND): Always link the ground pin of the microcontroller with the negative terminal of your external battery pack.
• Flyback Diode: If using a discrete transistor or MOSFET, always place a 1N4007 or Schottky diode in reverse-bias across motor terminals to snub voltage spikes.
