    DIY Digital Clock Soldering Kit 4-Digit LED Display with Temperature Sensor, 12H/24H Alarm & Memory Function, STEM Electronics Project for Adults (Blue)

    • (Electronic DIY Digital Clock): This product is a loose part and not a finished product. It is used to practice welding technology and can display functions such as date, time, temperature, and alarm clock. Let you experience the fun of welding and understand the principles of circuits during the welding process. After completion, it also looks great as a desktop decoration.
    • (Product Functions): On the right side of the product, three function keys are arranged vertically from top to bottom: Key 1 (Main Function Key): Long press to switch function modes; short press to adjust mode. Key 2 (Function Add Key): Adds functions in the adjustment mode of Key 1. Button 3 (Function Decrease): Simultaneously press buttons 2 and 3 in the time display interface [Test Method: Press button 1 to check if the display reacts. No change in the time display indicates successful setting]. Canceling the time and temperature alternating display uses the same method.The PCB board does not require soldering.
    • (Product parameters): This product comes with an acrylic shell and a voltage of 5V. The circuit board material of the product is double-sided 1.6mm RF-4 board. The silk screen identification on the circuit board is for your convenience in correctly soldering electronic parts.

    Why This Kit Stands Out?

    • Multi-Functional Display: 4-digit LED shows real-time clock (12/24H format), calendar date, and environmental temperature (?/? convertible). Features six-level brightness adjustment and power-loss memory via CR2032 backup battery.
    • Real-World Skills: Build a working electronic project while mastering SMD/SMT soldering techniques. Great for electronics hobbyists, homeschool curriculums or classroom STEM supplies.
    • Beginner-First Design:Pre-labeled PCB with polarity markers and corrosion-resistant pads.
    • Durable & Reusable:High-quality, fireproof PCB survives repeated soldering/desoldering.
    • Guided Learning:Step-by-step instructions + video tutorials ensure first-timers succeed.

    Important Usage Guidelines:

    • Prepare Tools First: Ensure you have a soldering iron and necessary tools ready before starting.
    • Avoid Overheating: Limit soldering iron contact to under 1 second per joint to prevent component damage.
    • Check Polarity: Verify positive/negative orientation of components before placement. Double-check component alignment and positioning before soldering.
    • Prevent Short Circuits: Keep conductive materials separated during assembly.
    • Prioritize Complex Parts: Install intricate components first for easier workflow management.
    • Static Safety: Use anti-static gloves or a wrist strap to protect sensitive electronics.
    • Review Instructions: Thoroughly read the included manual before beginning your project.
