Motorized PCB Soldering Holder Workstation with ESP32-S3 Touch Screen, Servo & Stepper Drive

Informazioni su questo modello

Overview Take your electronics workshop to the next level with this custom-designed, automated PCB Soldering Holder Workstation. Built for makers, electronics engineers, and DIY enthusiasts, this project combines 3D printing, custom electronics, and smart automation to streamline PCB assembly, soldering, and inspection. Key Features & Modular Design Smart Touch Interface: Features a 3.5-inch ILI9488 TFT display with an XPT2046 touch controller, managed by an ESP32-S3 microcontroller. Dual-Axis Actuation: Integrates a high-torque MG996R servo for tilting/positioning and a NEMA 17 stepper motor coupled with a lead screw mechanism for precise linear slide movement. Universal Hub Towers: Both the left and right towers feature universal mounting hubs. You can easily attach custom-designed modular accessories—such as a magnifying glass (lupa) or extra helping hands—tailored to your exact workspace needs. Built-in Workstation Tools: Includes integrated continuity testing (omomierz) with RGB LED status indicators and limit switches for safe positioning. Robust 3D Printed Structure: Engineered specifically for FDM printing with rigid mechanical tolerances and dedicated storage compartments for components.
